THRIFT-5248: Python: Make TSocket.isOpen check if server still connected

Client: py

This is inspired by changes to the Go library (THRIFT-5214) and, by
proxy, this blog post[1]. The idea is that if the other end of the
socket has closed their end of the connection, we can figure that out by
doing a non-blocking read on our socket before we waste time serializing
and sending a message just to find out the socket is closed when we try
to read the response.
