Change force_dhcp_release default to True

Historically it was was false because it requires the dnsmasq binary
'dhcp_release' which was not present in all distros.

Make ServersViewBuilderTest DRYer.

Move detail and brief info about server from test methods to setUp()
to expected_detailed_server and expected_server respectively. Every
test modifies the particular fields in the variables to create
appropriate test environment.

Fix mig 186 downgrade when using sqlalchemy >= 0.8

This patch fixes an issue that cause tests to break when using
SQLAlchemy 0.8 and newer. The migration was using non-existing column
names in an update query. Referring to a non-existent column in an
insert() or update() construct will raise an error instead of a warning
in SQLAlchemy 0.8.

As an added bonus - this patch adds the downgrade tests for migration
186 (which were missed in the original patch) to ensure there are no
further regressions.

Add validation of available_zone during instance create

When using nova boot command with --availability_zone parameter and only
input the zone without host and node, now will check if the zone is
available, if not, then return an error message directly rather than
create an instance with an Error state

Add a get_only_available option to function get_availability_zones

To disable available zone, one should have to disable both the scheduler
filter and the API extension, if the API extension is not disabled, this
patch will still do the validation of available zone

Sync models for AgentBuild, Aggregates, AggregateHost tables.

DB models definition should be up-to-date with DB schema obtained after
applying of migrations. Currently, there are no tests enforcing this and
it's really hard to analyze what indexes should be added, and what indexes
we have at the moment.

So the first step is it to fix all models, and add missing descriptions
about Indexes and UniqueConstraints in __table_args__ and use explicit
'nullable' parameter in columns description.

Add empty __table_args__ parameter to Table
