Fix subscription sharing for revised publishing intervalsv5.11.0-rc2v5.11.0
The current implementation uses an existing subscription for
sharing if a subscription with the requested publishing interval
exists. If the publishing interval of a subscription is revised
by the server, the lookup for a second monitoring with the same
requested interval fails and a new subscription is created.
This patch adds a member variable which stores the last revised
publishing interval to each backend. Requests with a publishing
interval < last revised publishing interval are "revised" by
the backend to ensure subscription sharing.
A test case which checks for correct subscription sharing is
added to tst_client.cpp.
