Remove migration constant job and test

Since openstack release naming conventions has changed, current test
which check data migration version will not work as expected and same
is also blocking our gate. Removing this job and test to unblock the
gate.

NOTE: Going forward glance PTL/team needs to change the database
migration version without fail at the start of release cycle.
