This patch adds support for migration of share servers. This migration is performed using a two-phase approach. Administrators are now able to request the migration of a share server within and across backends, with the possibility of chooosing a different share network for the destination share server. - A new field called `task_state` was added to the share server model in order to help the administrator to track the share server migration steps. A new field called `source_share_server_id` was added to link destination and source share servers. - A new periodic task was added to track migration of share servers and its resources. - Two new states were added: `server_migrating` and `server_migrating_to` to represent that share migration is in progress. - When performing the server migration, manila will not go to the scheduler, instead it will provide a request spec to drivers during migration check driver call. It'll be up to the driver validate if there is free space to handle the share server. - A new API called `share-server-migration-check' was added to check the feasibility of a migration, before actually triggering the start operation.
