Hans Lindgren c5e2d4b6b4 Remove unused provider firewall rules functionality in nova
Provider firewall rules functionality is not in use and hasn't been
for a very long time. The api for this was removed in [1] and db api
methods for adding/removing rows in the associated db table have not
been used since.

Stop refreshing those rules as it is essentially a no-op and indeed a
costly one that includes a rpc round trip to the conductor to get
back an always empty db result. This should have a positive impact on
instance boot performance since the conductor call happens to live
inside an externally syncronized block of code.

Removes related compute rpcapi/manager code that were missed in a
recent cleanup[2]. Since this functionality hasn't been in use since
Havana timeframe(!), it should be fairly safe to remove without first
deprecating it.

Also removes the now unused virtapi method provider_fw_rule_get_all()
and the virtapi itself from virt firewall driver initialization.
