Added test cases in ConfKeyManagerTestCase to verify fixed_key.

ConfKeyManagerTestCase sets the fixed_key option, but does not
perform checks to verify it was used.  This patch adds the
appropriate unit test cases to verify the fixed_key option.

Remove the unused _validate_device_name()

Since the commit I898ae56539c6101680983d1eca4bce6d92bd5ce6,
_validate_device_name() method has been unused.
This patch removes the method.

Use debug level logging in unit tests, but don't save them.

We want to try formatting debug level logs so we can gate on any
formatting errors, but we don't want to save the debug level logs as
there are just too many of them. So use fixtures.FakeLogger running at
INFO level and a custom NUllHandler at DEBUG level.

Not Using fixtures level parameter since that sets the log level for the
entire logger and not just the individual handlers.

Don't inherit from logging.NullHandler since it isn't in python2.6

Remove duplicate code from nova.db.sqlalchemy.utils

There is a lot of code in nova.db.sqlalchemy.utils which is also in
oslo-incubator's openstack.common.db.sqlalchemy.utils module so this
patch goes through and cleans up Nova.

Notable differences:

1. modify_indexes was nova-only but no longer used after the migration
   compaction work, so it's just removed here. It also didn't really
   work for mysql in cases where the index name was too long so it
   could be table-specific and therefore unusable in some mysql cases.
   See commit 029ebab for history.
2. create_shadow_table was not in oslo-incubator and it's also not
   currently used in nova after the migration compaction, however,
   I leave it here in case future migrations in Nova need to use it.
   This patch does replace the usage of _get_not_supported_column in
   create_shadow_table to use the same method from oslo's DB utils.
3. DeleteFromSelect is still used within nova.db.api per
   commit b36826e so we could move it to oslo-incubator but this
   patch leaves it for now since it's only used in Nova.
4. InsertFromSelect was introduced with commit 2e403b2 but now there
   is a copy in oslo-incubator so we can remove our usage in nova.
   However, oslo doesn't have the unit test that nova does, so the
   unit test has been moved to oslo with change I457acf33.
5. Oslo has is_backend_avail and get_connect_string methods so use
   those in test_migrations.py while doing this update.

Pass configured auth strategy to neutronclient

When the token is invalid Nova emits a log trace about an
unknown auth strategy (caused by neutron client). This is a
red herring and is only masking the fact that the token was
unable to be validated in the first place.

Instance groups: add method get_by_hint

In order to support backward compatibility a new method
'get_by_hint' has been added. This method will check if the
hint is a uuid and if no it will return get_by_uuid else it
will return get_by_name.

Remove unneeded call to fetch network info on shutdown

There is no reason to fetch the network_info from the network api on shutdown
since we can just pull it out of the local cache. There are probably other
places where this call to the network api call can be removed but this patch
just handles the case for shutdown.

Note: the following test was removed 'test_terminate_no_fixed_ips' as
the call to the network api is no longer done so this test would be the
same as test_terminate_no_network.

Return to using network_api directly for migrations

Previously, we added indirection APIs in conductor to wrap network
methods that still had direct-to-database calls that compute
manager couldn't make. Now that those are cleaned up, we can
remove the use of the indirection layer (and the layer itself from
conductor) and go direct to network_api again.
