df9b3c3b16 -fix mistake in _clear_cache 
git-svn-id: https://svn.code.sf.net/p/xcat/code/xcat-core/trunk@4432 8638fb3e-16cb-4fca-ae20-7b5d299a9bcd

cb2bef59b2 -When clearing DB handles, also clear the DB handle list 
-Correctly map the database handle per 'realautocommit' (was causing xCAT to be unable to survive even one database disconnect).
-Fix problem where mapping from database handles to dependent objects was not being updated when the database handles changed (was causing xCAT to be unable to survive more than one database disconnect).
-Put in more comments so that people may understand the unusable db handle recovery code
