Automate the clean up of orphan rows in the database catalogs during the db2ckupgrade processing.

We have been dealing with orphan rows in the database catalogs for many years now.  The first tool to deal with this was db2cleancat and it has gone through various iterations to address all of the various flavors of this type of issue and now has reached a point of maturity.  In fact, the recent release of Db2 has merged this functionality into the db2cat tool that ships with Db2. It should be possible to either completely automate this or add an option (a new flag) to trigger this clean-up automatically as part of the db2ckupgrade utility that detects that orphaned rows exist.  It might either prompt (orphan rows detected in the catalogs, clean up y/n?) or the user could pass a flag to do this automatically if they are detected during the db2ckupgrade. In theory, you could possibly just do it automatically and log that you did it in the d2ckupgrade.log and require NO user intervention.
