Implemented the unsubscribe for shared subscriptions.
What does this PR do?
Updates the CTrie.removeSubscriptionsFor to accept an UnsubscribeRequest instead of simple parameters, customizing the method to handle a shared subscription's unsubscribe request.
Adds a method removeSharedSubscriptionsForClient to remove in one step all the shared subscriptions of a session, in doing so it introduces a mapping cache clientId -> list of subscription to avoid a full tree traversal.
Why is it important/What is the impact to the user?
Implements part of MQTT5 shared subscription feature
