link event damper. - Link event damper running on each port will have its own SelectableTimer. This class helps create a mapping of SelectableTimer and object that created the SelectableTimer so that when timer is fired, proper EventHandler object can be invoked. HLD: sonic-net/SONiC#1071

damping config attr. - Adding serialization/deserialization logic for link event damping config so that when libsai is sending link event damping algo and config to syncd for set request, it uses serialization logic to serialize the requested data before sending the set request and when syncd receives the link event damping port attribute set request, it uses the deserialization logic to deserialize the data.
