Tooz integration
Manila currently uses file locks from oslo_concurrency to
coordinate operations racing with each other to perform a
particular action. In many situations, deployers may need a
distributed lock to a local file lock (or even a file lock living on
a shared file system). This need is accentuated if they were running
Manila services in HA or if they were using Share Replication across
AZs where manila-share services were running off different controllers
that would not be able to share a common oslo_concurrency
file lock or be protected against service/lock management failures.
Integrate Tooz library with helper methods to create a locking
coordinator and allow deployers to make the choice between file
and distributed locks.
Start the manila share service with Tooz backed coordination.
Replace the locks used for Share Replication work-flows in the
share manager to use Tooz based locks.
