Added TCP Server options and the following cli options as well:

• -tcp : to enable TCP server (default to stdio)
• -address: address for the tcp
• -port: port for the tcp

New debug options:

• -debug-jrpc2: enable logging for jrpc2
• -enable-log-jrpc2-file: enable file location logging for jrpc2
• -log-jrpc2-location: location to put tf-lsp-jrpc2.log in

I've been playing around with configuring the server with yaml/viper. I'll make sure to add these in as well.

Thinking about it, I'll add an issue and feature request to handle this formally.
