Allow service target to reach its own service

- Add loopback flows with prio 102 and extra match
- To service traffic when DIP is changed to nexthop
  also change SIP to service in service table
- When service target responds back it would appear like
  packet going back to service
- However in the service rev table we again change
  SIP to service ip and DIP to taget so the target
  will see the response as coming from service
