This is a follow up to b129511050
which changes the code block in the docs to python and also
cleans up some of the NumInstancesFilter documentation, specifically
removing wording around "running" instances because the filter
does not care about state, only the number of instances reported
against a host - they could be stopped/paused/etc.

Since blueprint return-alternate-hosts in Queens, the scheduler
returns a primary selected host and some alternate hosts based
on the max_attempts config option. The only reschedules we have
are during server create and resize/cold migrate. The list of
alternative hosts are passed down from conductor through compute
and back to conductor on reschedule and if conductor gets a list
of alternate hosts on reschedule it will not call the scheduler
again. This means the RetryFilter is effectively useless now since
it shouldn't ever filter out hosts on the first schedule attempt
and because we're using alternates for reschedules, we shouldn't
go back to the scheduler on a reschedule. As a result this change
deprecates the RetryFilter and removes it from the default list
of enabled filters.

This replaces with a reference to the down-cell

There was nothing clearly documented about move operations with
respect to AZ restrictions, i.e. when a server can move between
zones or not, and how forcing a target host during evacuate or
live migration can break tracking of the instance for it's orginally
intended zone. This adds documentation around that topic.

This patch adds a table of possible extra-spec/cpu_shared_set
combinations, and lists the expected behavior of instance emulator
threads for each case. This is an improvement over the previous doc,
which incorrectly implied that `share` was the default policy value,
and only covered what happens if cpu_shared_set is set.

This document was written back in the liberty release [1]
and says that conductor is not used for orchestrating the
resize/migrate flow, but given the description of how
conductor is used to orchestrate scheduling and reschedules
during a server create, it is unclear why the doc says that
resize is not used the same way since it is used for rescheduling
when prep_resize fails in a selected dest compute. This removes
the caveat to reflect reality.

The admin and user flavor docs on pci.alias were not super
helpful by just throwing the user to the config docs or

while in here.

The "availability_zone" parameter for server create in the
API reference and the availabilty zone user docs both say
that users should not use the default availability zone (nova)
yet our server create API samples use "nova" which is...bad.
This change fixes the API samples and related tests to use
a fake "us-west" availability zone. For any samples that were
requesting an AZ when creating a server, those are changed from
requesting "nova" to requesting "us-west" and a new
AvailabilityZoneFixture is added to stub out the code used to
validate the requested AZ and what is shown in server detail
responses.
Some unused samples are removed from the os-availability-zone
directory and the API reference and AZ user docs are updated for
formatting and linking to other docs for reference.

As discussed in the mailing list [1] since cells v1
has been deprecated since Pike and the biggest user
of it (CERN as far as we know) moved to cells v2
in Queens, we can start rolling back the cells v1
specific documentation to avoid confusing people
new to nova about what cells is and making them
understand there was an optional v1.
There are still a few mentions of cells v1 left in
here for things like adding a new cell which need
to be re-written and for that I've left a todo.
Users can still get at cells v1 specific docs from
published stable branches and/or rebuilding the
docs from before this change.

This adds a new config option to control the maximum number of disk
devices allowed to attach to a single instance, which can be set per
compute host.
The configured maximum is enforced when device names are generated
during server create, rebuild, evacuate, unshelve, live migrate, and
attach volume. When the maximum is exceeded during server create,
rebuild, evacuate, unshelve, or live migrate, the server will go into
ERROR state and the server fault will contain the reason. When the
maximum is exceeded during an attach volume request, the request fails
fast in the API with a 403 error.
The configured maximum on the destination is not enforced before cold
migrate because the maximum is enforced in-place only (the destination
is not checked over RPC). The configured maximum is also not enforced
on shelved offloaded servers because they have no compute host, and the
option is implemented at the nova-compute level.
