[autotest] Monitor the latency of heartbeat serialize/deserialize
Measure the latency for serializing/deserializing objects in heartbeat
between master and shards, and send the data to statsd server.
Serializing/deserializing Host object could become an overhead in the
future due to its dependency on other objects (epecially, AclGroup and
User), therefore, we should keep an eye on it.
