Lots of different things can be updating the same migration
record at the same time (different computes, the API, etc)
and we see DBDeadlock errors on migration_update at times
(and operators that do a lot of migrations have mentioned it
also) so this change simply adds the retry_on_deadlock decorator
to the migration_update DB API method.
