This introduces new OPENFLOW_SERVER-{address}:{port} diagstatus service
names in SwitchConnectionProviderImpl, where UdpHandler/TcpHandler
start.
The Thread is now named including the same -{address}:{port} suffix.
This is a counter-proposal to the idea of "add a channelFuture to
listen for when the channel is closed and then update diagstatus"
originally proposed in Ieb78f225c1fcdd2ebf72ad1a99a49d4993a6a5b6,
because if/when that channel is closed, the UdpHandler/TcpHandler
Runnable thread exits, so this will achieve the same result in a
more general safer way.
This may (TBC) indirectly also fix OPNFLPLUG-1057.
