When a LDAP user signs in the for the first time and if there
is an `Identity` object with `user_id` of `nil`, new users
will not be able to be register until that entry is cleared
because of the way identities are created:

1. First, the User object is built but not saved, so it has no `id`.
2. Then, `user.identities.build(provider: 'ldapmain')` is called,
   but it does not have an associated `user_id` as a result.
3. `User#save` is called, but the `Identity` validation fails if an
   existing entry with `user_id` of `nil` already exists.

The uniqueness validation for `nil` values doesn't make any sense in
this case. We should be enforcing this at the database level with a
foreign key constraint. To work around the issue we can validate
against the user instead, which does the right thing even when
the user isn't saved yet.

Refactor Hashed Storage for future Rollback functionality

See merge request gitlab-org/gitlab-ce!24402

Add the text `(moved)` to the `Closed` status indicator on a closed
issue if the reason the issue was closed was due to moving it.

This only applies to closed issues. Issues that were closed and moved
then later re-opened only show `Open`. This makes it more immidately
clear why the issue was closed.

Migrate jobs from `storage_migrator` to
`hashed_storage:hashed_storage_migrator`.

We need this new state for the Geo event logic in EE

Specs were reviewed and improved to better cover the current behavior.
There was some standardization done as well to facilitate the
implementation of the rollback functionality.

StorageMigratorWorker was extracted to HashedStorage namespace were
RollbackerWorker will live one as well.

This will serve as new base class for both Migrate and Rollback

This is part of the refactor to include a RollbackService into
HashedStorage module

We are keeping compatibility with existing scheduled jobs.
