Add a reference PTL guide to the contributor docs

This is a guide I used to help me throughout the cycle and I'm proposing it to the docs, in case it might help someone. Change-Id: I4f7600c908bf90395515f690b8eee0f9e7b0c9b0

 Chronological PTL guide
 =======================
 This is just a reference guide that a PTL may use as an aid, if they choose.
 New PTL
 -------
 * Update the nova meeting chair
  * https://github.com/openstack-infra/irc-meetings/blob/master/meetings/nova-team-meeting.yaml
 * Update the team wiki
  * https://wiki.openstack.org/wiki/Nova#People
 * Get acquainted with the release schedule
  * Example: https://wiki.openstack.org/wiki/Nova/Stein_Release_Schedule
 Project Team Gathering
 ----------------------
 * Create PTG planning etherpad, retrospective etherpad and alert about it in
  nova meeting and dev mailing list
  * Example: https://etherpad.openstack.org/p/nova-ptg-stein
 * Run sessions at the PTG
 * Have a priorities discussion at the PTG
  * Example: https://etherpad.openstack.org/p/nova-ptg-stein-priorities
 * Sign up for group photo at the PTG (if applicable)
 * Open review runways for the cycle
  * Example: https://etherpad.openstack.org/p/nova-runways-stein
 After PTG
 ---------
 * Send PTG session summaries to the dev mailing list
 * Make sure the cycle priorities spec gets reviewed and merged
  * Example: https://specs.openstack.org/openstack/nova-specs/priorities/stein-priorities.html
 * Run the count-blueprints script daily to gather data for the cycle burndown chart
 A few weeks before milestone 1
 ------------------------------
 * Plan a spec review day
 * Periodically check the series goals others have proposed in the “Set series
  goals” link:
  * Example: https://blueprints.launchpad.net/nova/stein/+setgoals
 Milestone 1
 -----------
 * Do milestone release of nova and python-novaclient (in launchpad only)
  * This is launchpad bookkeeping only. With the latest release team changes,
    projects no longer do milestone releases. See: https://releases.openstack.org/reference/release_models.html#cycle-with-milestones-legacy
  * For nova, set the launchpad milestone release as “released” with the date
 * Release other libraries if there are significant enough changes since last
  release. When releasing the first version of a library for the cycle, bump
  the minor version to leave room for future stable branch releases
  * os-vif
 * Release stable branches of nova
  * ``git checkout <stable branch>``
  * ``git log --no-merges <last tag>..``
    * Examine commits that will go into the release and use it to decide
      whether the release is a major, minor, or revision bump according to
      semver
  * Then, propose the release with version according to semver x.y.z
    * X - backward-incompatible changes
    * Y - features
    * Z - bug fixes
  * Use the new-release command to generate the release
    * https://releases.openstack.org/reference/using.html#using-new-release-command
 Summit
 ------
 * Prepare the project update presentation. Enlist help of others
 * Prepare the on-boarding session materials. Enlist help of others
 A few weeks before milestone 2
 ------------------------------
 * Plan a spec review day (optional)
 * Periodically check the series goals others have proposed in the “Set series
  goals” link:
  * Example: https://blueprints.launchpad.net/nova/stein/+setgoals
 Milestone 2
 -----------
 * Spec freeze
 * Release nova and python-novaclient
 * Release other libraries as needed
 * Stable branch releases of nova
 * For nova, set the launchpad milestone release as “released” with the date
 Shortly after spec freeze
 -------------------------
 * Create a blueprint status etherpad to help track, especially non-priority
  blueprint work, to help things get done by Feature Freeze (FF). Example:
  * https://etherpad.openstack.org/p/nova-stein-blueprint-status
 * Create or review a patch to add the next release’s specs directory so people
  can propose specs for next release after spec freeze for current release
 Non-client library release freeze
 ---------------------------------
 * Final release for os-vif
 Milestone 3
 -----------
 * Feature freeze day
 * Client library freeze, release python-novaclient
 * Close out all blueprints, including “catch all” blueprints like mox,
  versioned notifications
 * Stable branch releases of nova
 * For nova, set the launchpad milestone release as “released” with the date
 Week following milestone 3
 --------------------------
 * Consider announcing the FFE (feature freeze exception process) to have people
  propose FFE requests to a special etherpad where they will be reviewed and
  possibly sponsored:
  * https://docs.openstack.org/nova/latest/contributor/process.html#non-priority-feature-freeze
  * Note: if there is only a short time between FF and RC1 (lately it’s been 2
    weeks), then the only likely candidates will be low-risk things that are
    almost done
 A few weeks before RC
 ---------------------
 * Make a RC1 todos etherpad and tag bugs as ``<release>-rc-potential`` and keep
  track of them, example:
  * https://etherpad.openstack.org/p/nova-stein-rc-potential
 * Go through the bug list and identify any rc-potential bugs and tag them
 RC
 --
 * Do steps described on the release checklist wiki:
  * https://wiki.openstack.org/wiki/Nova/ReleaseChecklist
 * If we want to drop backward-compat RPC code, we have to do a major RPC
  version bump and coordinate it just before the major release:
  * https://wiki.openstack.org/wiki/RpcMajorVersionUpdates
  * Example: https://review.openstack.org/541035
 * “Merge latest translations" means translation patches
  * Check for translations with:
    * https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:zanata/translations
 * Should NOT plan to have more than one RC if possible. RC2 should only happen
  if there was a mistake and something was missed for RC, or a new regression
  was discovered
 * Do the RPC version aliases just before RC1 if no further RCs are planned.
  Else do them at RC2. In the past, we used to update all service version
  aliases (example: https://review.openstack.org/230132) but since we really
  only support compute being backlevel/old during a rolling upgrade, we only
  need to update the compute service alias, see related IRC discussion:
  http://eavesdrop.openstack.org/irclogs/%23openstack-nova/%23openstack-nova.2018-08-08.log.html#t2018-08-08T17:13:45
  * Example: https://review.openstack.org/642599
  * More detail on how version aliases work: https://docs.openstack.org/nova/latest/configuration/config.html#upgrade-levels
 * Write the reno prelude for the release GA
  * Example: https://review.openstack.org/644412
 * Write the cycle-highlights in marketing-friendly sentences and propose to the
  openstack/releases repo. Usually based on reno prelude but made more readable
  and friendly
  * Example: https://review.openstack.org/644697
 Immediately after RC
 --------------------
 * Look for bot proposed changes to reno and stable/<cycle>
 * Create the launchpad series for the next cycle
 * Set the development focus of the project to the new cycle series
 * Set the status of the new series to “active development”
 * Set the last series status to “current stable branch release”
 * Set the previous to last series status to “supported”
 * Repeat launchpad steps ^ for python-novaclient
 * Register milestones in launchpad for the new cycle based on the new cycle
  release schedule
 * Make sure the specs directory for the next cycle gets created so people can
  start proposing new specs
 * Make sure to move implemented specs from the previous release
  * Use ``tox -e move-implemented-specs <release>``
  * Also remove template from ``doc/source/specs/<release>/index.rst``
  * Also delete template file ``doc/source/specs/<release>/template.rst``
 * Create new release wiki:
  * Example: https://wiki.openstack.org/wiki/Nova/Train_Release_Schedule
 Miscellaneous Notes
 -------------------
 How to approve a launchpad blueprint
 ************************************
 * Set the approver as the person who +W the spec, or set to self if it’s
  specless
 * Set the Direction => Approved and Definition => Approved and make sure the
  Series goal is set to the current release. If code is already proposed, set
  Implementation => Needs Code Review
 * Add a comment to the Whiteboard explaining the approval, with a date
  (launchpad does not record approval dates). For example: “We discussed this
  in the team meeting and agreed to approve this for <release>. -- <nick>
  <YYYYMMDD>”
 How to complete a launchpad blueprint
 *************************************
 * Set Implementation => Implemented. The completion date will be recorded by
  launchpad
