Fix matchmaker_redis: ack_alive fails with KeyError on re-registration
attempt.
def ack_alive(self, key, host):
topic = "%s.%s" % (key, host)
if not self.redis.expire(topic, CONF.matchmaker_heartbeat_ttl):
# If we could not update the expiration, the key
# might have been pruned. Re-register, creating a new
# key in Redis.
self.register(self.host_topic[host], host)
self.host_topic is a dict with keys of tuple (key, host), not 'host',
register's first parameter is the topic like 'notification-info',
so modify it to key.
And it will not cause indefinite recursion, because when register end,
the key exist in redis, redis.expire will return True.
Add test case for ack_alive.
