Defines interface for DB access.
The underlying driver is loaded as a LazyPluggable.
Functions in this module are imported into the manila.db namespace. Call these functions from manila.db namespace, not the manila.db.api namespace.
All functions in this module return objects that implement a dictionary-like interface. Currently, many of these objects are sqlalchemy objects that implement a dictionary interface. However, a future goal is to have all of these objects be simple dictionaries.

A snapshot is supposed to be truly ‘available’ when it is available across all of the share instances of the parent share object. In case of replication, we only consider replicas (share instances) that are in ‘in_sync’ replica_state.

Register Models and create metadata.
Called from manila.db.sqlalchemy.__init__ as part of loading the driver, it will never need to be called explicitly elsewhere unless the connection is lost and needs to be reestablished.
Tests are lacking for the db api layer and for the sqlalchemy driver. Failures in the drivers would be detected in other test cases, though.
