This change adds in the nova_api db migration that has to happen
within mitaka. This is a new required DB though the DB entry has
existed since Kilo.
Change:
* The SHA was moved forward to the new version of nova to support
this change. This was done independently of the rest of the stack
to ensure functionality of this new DB.
* An entry was added to the secrets file to support a new db user
and password.
* The requirements repo was rev'd forward to support the new
requirements within nova.
