endpoint_cnt object is created during network create and destroyed when
network is deleted. But the updateToStore function creates an object
when it is not present in the store. endpoint_cnt is a mutable object
and is updated during endpoint create and delete events. If endpoint
create or delete happens after the network is deleted, it can
incorrectly create an endpoint_cnt object in the store and that can
cause problems when the same network is created again later.
The fix is to not create the endpoint_cnt object when endpoint_cnt is
incremented or decremented

During ungraceful shutdown, it is possible that the endpoint_cnt can be
inconsistent with the actual endpoints in a network. This fix will
resolve that inconsistency

Currently endpoint count is maintained as part of
network object and the endpoint count gets updated
frequently while the rest of network is quite stable.
Because of the frequent updates to endpoint count the
network object is getting marshalled and unmarshalled
ferquently. This is causing a lot of churn and transient
memory usage. Fix this by creating a deparate object of
endpoint count so that only that gets updated.
