Use region for cinder management uri

Make the cinder client region-aware since Rackspace supports
more that one and needs to know in which region to deploy
volumes.

Enable better sub-classing of common Schema class

This patch is first in a series of patches to unify the code for
property and parameter validation based on a common Schema class.

The current patch refactors the existing Schema class in
constraints.py so it will in a subsequent patch be easier to
sub-class it, i.e. to rebase the parameters schema class on it.

For example, sub-classes will be able to override uppercase/
lowercase spelling of data type names etc., which will save us
translation between CFN and HOT specifics in the engine.

Add a new "UpdateWaitConditionHandle" resource

On Update, the WaitConditions are not waited on if the count of unique ids
have already been satisfied before. If you have a setup which is watching
for changes and re-sending the signals then, it simplifies things for
the stack update to wait for these to be completed before moving on.

Remove dependencies on pep8, pyflakes and flake8

Hacking already pins them to the compatible versions,
so avoid running out of sync by letting hacking
determine the correct code checker versions.

Fix order of arguments in assertEqual (patch 2/2)

Some tests used incorrect order assertEqual(observed, expected).

The correct order expected by testtools is
assertEqual(expected, observed).

This patch includes the other half of the files touched by these changes
(starting from test_n* plus contrib code) to ease the review.

Database model for software config/deployment

These database tables act as storage to SoftwareConfig
and SoftwareDeployment entities which are exposed via the
heat REST API.

There is no software_config_update as software config entities
are immutable after creation. This allows them to be created
outside any stack which uses them, and used by reference without
being concerned about their contents changing over time.

Refactor heat gate testing contrib support

The existing code is running tests twice, one for heat, one for
contrib via adding two commands in tox.

This breaked tox single run. For example:

  tox -e py27 -- heat.tests.test_software_config

Except heat.tests.test_software_config is executed, all test cases in
contrib will be executed also.

The patch added contrib in discover list, which can make sure both
contrib in heat gate testing and does not break single test run.

Fix adding heat_stack_user role via v3 API

A regression was introduced via 301a894 because it expects
keystoneclient functionality which is not yet merged/released,
so instead of passing the name to roles.list() we must filter
the results locally to lookup the role ID.

The lack of filtering support is a general issue with the v3
keystoneclient interfaces, so when it's fixed we can remove
this workaround.

Always specify preserve_ephemeral on server rebuild

Heat unit tests currently fail with git master novaclient. Without
this change all heat gating will fail as soon as novaclient 2.16.0 is
released.

Ideally the test mox should handle preserve_ephemeral being specified or not
but it is not obvious that this is possible. Novaclient rebuild has a kwargs
so always specifying preserve_ephemeral should not have any issues with
older novaclient.

Make LB-updating in rolling update more reliable

The rolling update code updates the load balancer when instances
are being updated (and thus out of service). It determines which instances
are being changed by comparing the str() of the templates. Unfortunately,
str() of dicts in Python returns keys in an unreliable order, depending on
the way the dicts were constructed. Therefore, sometimes rolling updates
would erroneously determine that instances were changing when they were not,
and take them out of service in the load balancer.

This patch contains no additional tests because it's not really possible to
reliably reproduce this across multiple platforms. Existing tests will fail if
the erroneous case is triggered.
