Optimizer rule should be able to specify to optimizer framework about how many times it should
be invoked
---------------------------------------------------------------------------------------------------------

                 Key: PIG-2350
                 URL: https://issues.apache.org/jira/browse/PIG-2350
             Project: Pig
          Issue Type: New Feature
            Reporter: Ashutosh Chauhan


Currently framework keep invoking rule until it says false. There are few rules (which actually
aren't optimization) which needs to be applied exactly once. As a workaround these rules keep
a boolean which they set to true first time they are called and then check it later. We should
get rid of such hacks.
