Remove ovn-dbs temporary container

With I918b6c16db6ed70d9ad612aecd7af7d725520f7b we moved the ovn-dbs
creation out of the ephemeral ovn_dbs_init_bundle container and on to
the host.

We left the ovn_dbs_init_bundle container around and kept the tag
ovn_dbs_remove_old_cruft for it. This is because with that tag
we historically triggered the needed code to make sure to handle
the transition from a deployment where ovn-dbs used the internal_api
VIP to the (current) deployment where ovn-dbs uses its own VIP.

Since ovn-dbs has its own VIP starting with train, we can now safely
drop this container.
