Turn on base image cleanup by default.

Essex shipped with the libvirt image cache manager hobbled so it
wouldn't delete unused base images. Its been a while and we haven't
had a new bug reported in ages. Let's turn it on for Folsom. This
is tracked by bug 1029674.

reduce debugging from utils.trycmd()

In the case where the command fails, we're returning
the err anyway and the caller can log if required.

In the discard_warnings=True case, then the caller
has explicitly asked to suppress the warnings,
so don't log this noise either.

sync openstack-common log changes with nova

don't throw exceptions if %(color)s tag is used

fixes bug #1030078

If the log format strings include the %(color)s key in them and you
enable file logging, your log files won't work, and instead you'll
see exceptions on the console as the default python log handler doesn't
support that keyword.

This approach stubs out the extra keywords to be empty strings to avoid
the KeyError. Tests are also added to demonstrate the KeyError as defined
behavior, and test that color codes can be passed.

Compute: VM-Mode should use instance dict.

Instance dicts no longer support attribute-style access.

Convert virtual_interfaces to using instance_uuid.

This review converts virtual_interfaces from tracking their
instances with instance_id to using instance_uuid.

This should be the last review for blueprint finish-uuid-conversion.

Send a full instance in reset_network.

Change the reset_network method of the compute
rpc API to take a full instance over rpc instead of just
the instance UUID.  This cuts down on database access needed
by nova-compute.

Send a full instance in rollback_live_migration_at_destination.

Change the rollback_live_migration_at_destination method of the compute
rpc API to take a full instance over rpc instead of just
the instance ID.  This cuts down on database access needed
by nova-compute.

This was the last method of this API that was taking an instance ID
as an argument.  There still some left that take the instance UUID,
but I can see the light at the end of the tunnel.

Fix arg to get_instance_volume_block_device_info().

Michael Still caught this bug while reviewing an earlier patch in this
patch series.  This code was passing an instance ID to this function,
but it expects an instance UUID.

Not really related to, but tied up in the patch series
for blueprint no-db-messaging.
