    Call central's update_status correctly

    * Cleaned up the way pool manager calls central's
    update_status for create, delete and update.
    * Cleaned up pool manager's update_status
    * Added some more information to logging statements
    when central's update_status and pool manager's
    update_status are called
    * When a domain is deleted, I see SERVFAIL too being
    returned by BIND. Added that to the list of error codes
    to check
    * memcache does not seem to store a value of None.
    Worked around that bug.
    * Updated unit tests
