Add a log4j category for all edits to META/ROOT
-----------------------------------------------

                 Key: HBASE-5238
                 URL: https://issues.apache.org/jira/browse/HBASE-5238
             Project: HBase
          Issue Type: New Feature
          Components: regionserver
    Affects Versions: 0.94.0
            Reporter: Todd Lipcon
            Priority: Minor


Occasionally we run into bugs that have corrected META and written some bad 
data to META/ROOT but it's difficult to understand the order in which things 
happened. One option is to dump the HLog contents from the servers that hosted 
META at that time, but then it's interspersed with all other data. It would be 
nice to add a Log4j Logger to which we log all edits being applied to META and 
ROOT in textual form at DEBUG level. Then it would be easier to do a 
cluster-wide log grep to see what happened when.
