Add read/write metrics to TimedValueMarshaller

The following metrics were added:
* cache/chroniclemap/store_serialize_latency_<cache-name> the latency of
  serializing entries in chronicle-map store
* cache/chroniclemap/store_deserialize_latency_<cache-name> the latency
  of deserializing entries in chronicle-map store

Notes:
* metrics are not serializable hence as such they have to be transient
* in case 'readResolve' method is used instead of constructor fallback
  to metrics cache to get metrics; it is safe operation as store is
  created only after the TimeValueMarshaller is created for a cache in
  question hence metricsCache is going to have the corresponding entry
