Taskmanager says "Successfully created DNS entry" when trove dns support = False

[Masaki Matsushita]

Taskmanager says "Successfully created DNS entry for instance" in tr-tmgr.log when DNS support is disabled like following:

2015-08-25 17:51:43.925 DEBUG trove.taskmanager.models [-] trove dns support = False from (pid=3812) _create_dns_entry /opt/stack/trove/trove/taskmanager/models.py:890
2015-08-25 17:51:43.925 DEBUG trove.taskmanager.models [-] <greenlet.greenlet object at 0x7f4db6d4a370>: DNS not enabled for instance: 6c3e153f-43b1-4352-a7c0-68a74c547c74 from (pid=3812) _create_dns_entry /opt/stack/trove/trove/taskmanager/models.py:929
2015-08-25 17:51:43.925 DEBUG trove.taskmanager.models [-] Successfully created DNS entry for instance: 6c3e153f-43b1-4352-a7c0-68a74c547c74 from (pid=3812) create_instance /opt/stack/trove/trove/taskmanager/models.py:433

I think this behavior is confusing.

    Fix not to output confusing message in tr-tmgr.log

    Taskmanager outputs the message "Successfully created DNS entry for
    instance" in tr-tmgr.log even though DNS support is disabled.
    This change fix to output that message only when DNS support is
    enabled.
