GEODE-3636: Fixing hang shutting down gateway sender with SSL

The gateway sender shutdown code calls connection.destroy to interrupt the ack
reader thread. Connection.destroy was calling socket.shutDownOutput.
SSLSockets do not support socket.shutDownOutput() resulting in connections not
being destroyed. This left the AckReaderThread stuck on read holding a
readLock, which prevented the stopper thread from getting a writeLock.

> SSLSockets throw the following exception if shutdownOutput() invoked:
> java.lang.UnsupportedOperationException: 
> The method shutdownOutput() is not supported in SSLSocket
> GatewaySender code tries to interrupt the AckReaderThread in the middle of a socket read by calling Connection.destroy. Unfortunately, that throws and then swallows this UnsupportedOperationException and doesn't close the socket when SSL is enabled.
