Eliminate duplicated LoopingCall and LoopingCallDone code

Bug 1307560 cleaned up some parts of this particular use of deprecated
code. However there is still one instance left in
trove/common/utils.py which needs to be cleaned out. This change
removes LoopingCall and LoopingCallDone from utils.py and references
the openstack code from loopingcall.py.
