Douglas Viroel 39efc2bde8 Add share server migration
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.
