  ovn-nbctl: add --may-exist/--if-exists options for policy routing

Introduce the following options to avoid error reporting for policy
routing:
1) --may-exist: the lr-policy-add does not result in an error if a policy
   with the same priority and match string is already present
2) --if-exists: the lr-policy-del does not result in an error if a policy
   with the specified uuid is not present in the db
