    Use restore heat_ prefix for shared-db relation

    Heat is staying in status blocked Missing relation database when
    doing an upgrade from stable to next. Missing required data:
    database_password. The relation is actually passing heat_password.

    Commit 1bdc87f495898be3a9877f0a14528ce48c27f3f0 removed the heat_
    prefix. This changes restores the heat_ prefix to allow stable to
    next upgrades to work.
