Update to Quantum Client 2.2.0

This patch updates tools/pip-requires to use the python-quantumclient 2.2
It also limits the version to <3.0.0 to prevent breaking something accidently
when 3.0.0 is released.

Prepare services index method for use with cells

Move the api.openstack.compute.contrib.services' index method's logic
out of the openstack api layer and into the compute api layer.

The addition of the availability_zone information is already done by the
host api. For this reason it was removed from the openstack api layer.
The behaviour of the call remains the same, only the functionality has
been moved.

This patch makes the functionality automatically work in cells.

Fix behaviour of split_cell_and_item

If you try to split a cell and item, with no path!to!cell@ in it, it'll
now return None for the cell, instead causing a ValueError when trying
to split the result.

Add missing tests for db.block_device_mapping_* methods

There was no tests in test_db_api for block_device_mapping_* methods.
Add tests to ensure that all works. Also these tests allow us to refactor
work with session in these methods.

Fix bug in is_ephemeral we should return True or False not instance of
_sre.SRE_Match or None.

Refactor work with session in db.block_device_mapping_* methods

Remove explicit use of session where it is not required.
Also this is small performance optimization, because if we put
session parameter to Models.save() method will create subtransaction.

Make run_instance() bail quietly if instance has been deleted

Right now, we make a big mess in the logs if someone deletes an
instance before we get a chance to run it. This cleans that up
to a single warning message.

Don't load system_metadata when it isn't joined.

If we always load system_metadata, it will throw a sqlalchemy
error if it isn't joined in the column. Rather than putting it
in extra keys we need to explicitly join it if it is missing.

Adds a test to make sure that system_metadata is returned
properly from the migration call even though the extra keys
parameter was removed.

List ComputeHostNotFound as a client exception

service_get_all_by() in nova.conductor.manager should list
ComputeHostNotFound as a client exception for rpc. This to prevent
the rpc layer from logging a traceback when this exception is raised.
This is an expected type of exception that should be left to the
client to handle.

Resolves bug 1154597.

Fix use of potentially-stale instance_type in tenant_usage

The simple_tenant_usage API extension may return incorrect billing
information if a flavor is changed or deleted while an instance using
it is still running. This makes it use the stashed instance_type instead.
