Socket message structure

[foolishsailor]

*** DRAFT ***

This is a new propsed socket message structure

• Abstracts logic out of socket object
• Uses reducers and actions to process all message maintaining type safety
• Breaks message into 3 categories: Command, State and Message
• Only the commands are detailed here but a simple copy/paste to flesh out sekeltons for remainder

Have a look as this is the direction Im taking ai-lens and want to make as easy as possible to drop in a socket server module into a devs project and they can just pop in the business logic into the various exposed functions

note: this is built on top of the previous PR. For the purposes of this PR the only relevant changes are within the socket-server folder
