Bence Romsics 648ab82a4b New agent attribute: resources_synced
Agents supporting the guaranteed minimum bandwidth feature need to share
their resource view with neutron-server and in turn with Placement too.
The resource information is synchronized to neutron-server via the
periodic agent heartbeat therefore transient synchronization errors are
fixed by the next heartbeat. But synchronization to Placement is not
done periodically, but on a (mostly) on demand basis. Therefore to fix
transient errors of the synchronization to Placement we must remember
the success/failure of the last synchronization attempt.

This change implements the extension 'agent-resources-synced' and
therefore extends the agent db model and object with a new attribute:
'resources_synced'. This attribute in only meant to be updated
internally. But it can be read via the API for debugging purposes.

APIImpact: The agent resource has a new attribute: resources_synced.
