This adds two columns to the `recording_session` table. One column is a
foreign key to the `iam_user_hst` table and the other is a foreign key
to the `iam_scope_hst` table. The foreign key to the `iam_scope_hst`
table reference the IAM scope the user belongs to at the time of the
recording.
This moves and renames the migration with the session recording table to
come after the history table migrations. This allows the session
recording table to have foreign key references to the history tables
without using alter table statements.
Add the following new tables used for storing session recordings:
* recording_session
* recording_connection
* recording_channel
* recording_channel_ssh
* storage_bucket
