Julien Danjou bc11f09b83 Rewrite heartbeat runner with event 
The current implementation uses an event attached to the Heart class to detect
if the thread is done. Since the thread is a daemon, it might be killed after
the interpreter is done, especially if an application is killed before calling
stop() on the coordinator. This results in the following backtrace:

Exception in thread Thread-1 (most likely raised during interpreter shutdown):
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
  File "/usr/lib/python2.7/threading.py", line 754, in run
  File "/usr/local/lib/python2.7/dist-packages/oslo_utils/excutils.py", line 250, in wrapper
  File "/usr/local/lib/python2.7/dist-packages/tooz/coordination.py", line 206, in _beat_forever_until_stopped
  File "/usr/lib/python2.7/threading.py", line 585, in set
  File "/usr/lib/python2.7/threading.py", line 407, in notifyAll
<type 'exceptions.TypeError'>: 'NoneType' object is not callable

This patches simplifies the heart class by using the thread status rather than
an event to check if it's alive and wait for it to stop.
