GEODE-6287: Cleaned up FilterProfile clientMap when client disconnects normally
> When a client connects, registers interest and disconnects normally, its
> ClientProxyMembershipID is not cleaned up and a memory leak occurs
> -------------------------------------------------------------------------------------------------------------------------------------------

> When a client connects to a distributed system and registers interest, the
> Region's FilterProfile's clientMap (an IDMap) registers the
> ClientProxyMembershipID in both the realIDs and wireIDs like:
> {noformat}
> realIDs={identity(192.168.2.12(client-register:52879:loner):63013:2327c553:client-register,connection=2=1};
> wireIDs={1=identity(192.168.2.12(client-register:52879:loner):63013:2327c553:client-register,connection=2}
> {noformat}
> When the client leaves normally, the UnregisterInterest command is invoked
> which removes the interest and the region. Part of that behavior is to remove
> the regionName from the set of regions.
> {noformat}
> this.regions.remove(regionName)
> {noformat}
> Then ClientInterestList.clearClientInterestList is then invoked which is
> supposed to clear the FilterProfile for each region, but the regions are
> already cleared by the UnregisterInterest command, so this method doesn't do
> anything.
> Then, LocalRegion.cleanupForClient is invoked which invokes
> FilterProfile.cleanupForClient. This method currently only closes CQs (which
> also cleans up the cqMap which is also an IDMap like the clientMap).
> At the end of this, the clientMap's realIDs and wireIDs still contain the
> ClientProxyMembershipID.
> The cleanupForClient method could be changed to also clean up the clientMap.
> Note: If the client is killed abnormally, the UnregisterInterest command is
> not invoked, so the interest and the region is not cleaned up normally. When
> ClientInterestList.clearClientInterestList is called, the set of regions
> still contains the region, and the IDMap is cleaned up properly.
