GEODE-3416: Reduce synchronization blockages in SocketCloser.
Remove synchronization blocks around HashMap. Replace that implementation
with simpler ThreadPool that is not unbounded and does not grow as the
number of remoteAddress (clients/peers) are added

> In the SocketCloser.asyncClose method, there is a synchronization block around at HashMap.
This synchronization will cause an effective single-threaded processing capability when closing
sockets. this effect becomes more evident with a high number of clients.
