Rename private functions in db.sqla.api

instance_get_all_by_filters() called 3 helper functions: exact_filter,
regex_filter and tag_filter. None of these functions had any other
callers.

This change prefixes them with _ to identify them as private.
Additionally, it removes the model arguments to the functions as these
always relate to an Instance and/or its InstanceMetadata.
Consequently, the functions are renamed to identify them as specific
to an Instance query. exact_filter is moved from the top of the module
to be next to the other 2.

Assert order of DB index members

Order of columns can matter. Most SQL databases can use the leading
columns for optimizing queries that don't include all of the columns.
Ignoring the order can result in an index being added that may not
be able to be used to optimize the same queries.

Adds global API version check for microversions

Adds a check for a request that the version requested is within the
global API version range supported by the REST API. Both the minimum
and maximum are currently set to "2.1". The maximum will be increased
everytime an API change is made.

Also sets up some template/doc files for clearly documenting
the REST API changes with each microversion increment.

Partially implements blueprint api-microversions

Libvirt normalize numa cell ids

This patch normalizes the cell ids before writing xml.

they need to be normalized before writing xml, or otherwise
the xml will be invalid.

Cleanup timeutils override in tests/functional/test_servers

The ServersTest._force_reclaim helper method sets up a timeutils
override but never removes it. This allows the override to potentially
leak into other tests causing spurious failures in completely unrelated
tests.
