tpClient crashes on network loss

[sjstein]

During a router reboot, the following error was noted:

20200525 00:19:06 [WARN] Timeout waiting for server response. {tpMonitor.py} Traceback (most recent call last): File "tpMonitor.py", line 101, in data = s.recv(1024) ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

Add exceptclause to catch, delay, and retry connection until either success or user interrupt.

This error can be kind of be recreated by halting the server process while the client is running, however yields a different error:

Traceback (most recent call last): File "tpMonitor.py", line 94, in s.sendall(MSG_READ_ALL) ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

It appears the first error noted in the original issue comment happened while the client was waiting for a message, wherein the message in this comment happened while the client was attempting to send the query
