Add FRC Driver Station connection support.

Browse Source 
The 2017 FRC Driver Station supports getting the robot IP via a TCP
connection that returns JSON.  Use this to support overriding the
server IP address used for client connections.

Default to using this approach for client connections in the NetworkTable
interfaces.

Add support for setting the server address without stopping and
restarting the client.

SetTeam now also round-robins by default.
