The placement API will initially host resource provider
information and then will grow to provide a full placement
service. Eventually it will be fully extracted from Nova.
To facilitate that extraction, this service is being developed
with few ties to existing nova.wsgi structures. Instead it
uses relatively plain WSGI apps that are:
* uses the Routes library with declarative mapping defined in
ROUTE_DECLARATIONS
* basic wsgi apps, with webob and the request class, for each handler
define as functions
* does not use a paste-ini file to compose middleware, instead code
which minimally inspects the oslo config to know how to adjust
middleware (in the initial case choosing an auth_strategy)
Many of these "features" will be demonstrated in commits that
follow this one that enable specific behaviors for resource
providers and their inventories.
In order to ensure that this change can be merged in an atomic
fashion it includes microversion support that was previously in its
own commit.
The microversion_parse library is used in a WSGI middleware
to parse incoming microversion headers and place the
determined value into the WSGI environment at the
'placement.microversion' key. Response headers are adjusted to
add the required outgoing headers as described in:
http://specs.openstack.org/openstack/api-wg/guidelines/microversion_specification.html
If a client requests an invalid microversion, they will receive
a 400 response. If the microversion is of a valid form but not
available, they will received a 406 response. The format of that
response is dependent on the accept header of the request. If it
is JSON, the min and max available microversions are presented.
A request to '/' will return version discovery information.
Thus far nothing else is done with the microversion information.
It is there for when we need it in the future. For now everything
is version 1.0.
The groundwork for using gabbi to test the API is in place in
nova/tests/functional/api/openstack/placement. The gabbi tests
are included in the functional target. To run just the placement
tests it is possible to run 'tox -efunctional placement'.

os-api-ref is released on pypi now, so we can move to using it instead
of our in tree version. All future extension fixes will happen over
there instead of here.

Since reno is the new tool for Relnotes [1], we need to add it
to Nova and provide some Sphinx docs for Liberty and Mitaka.

This removes the one seqdiag that is in our docs which drops the whole
chain of sphinxcontrib-seqdiag which requires Pillow, which requires
that you have a C compiler and jpeg-dev package on your environment to
build documenation for a python project.

os-testr has a blacklist we can use to specify which
tests to avoid. It uses "testr run --parallel" so tests
are run in parallel as well. We also get rid of the
huge list of tests in tox.ini into a separate file.
<soap_box>
The reason for using a black list is that when new tests
are being added, they are automatically either fixed to
work under python34 or added to a well known list of
tests so whoever is working on python34 can try to fix
those tests over a period of time. Hoping really that
this black list shrinks over time quickly. This is also
a pool of low hanging tasks that folks when they have
some time to pull a few tests from here and fix them.

As discussed in the Liberty Design Summit "Moving apps to Python 3"
cross-project workshop, the way forward in the near future is to
switch to the pure-python PyMySQL library as a default.

The diagrams were hard to read and update. Replaced them with
simplified diagrams and tables. I used the content as is. I looks
inconsistent to me, but should now be easier to change.

This change adds a basic bandit config for Nova. It can be invoked
by running the tox environment for bandit;
tox -e bandit
This is intended as a starting point for using bandit with Nova
and it should be revisited to improve the testing as more is learned
about the specific needs of the Nova code base.
Tox is configured to only show results for high and medium severity
results.
