Refactor: Handling of multiple server instances

[Ren-B-7]

In the event where multiple server instances were to be opened. Theres no way to cleanly keep track or handle changes to others

Meaning in most cases the other server Obj would be over written and closed, which is sub-optimal. Since we dont know if they get closed properly. Also it wont allow for multiple server instances to be opened in one Neovim session under current conditions, even if the port were to be changed.

Is this the expected behaviour or can we improve on this?

Yes, it is expected, because the plugin doesn't even allow different ports (yet)

I have been slowly adding port options to the start and pick commands (pick hasnt been added to any pr's yet, as i dont want to overload that pull request).

But i fully believe we can add multi-server functionality in the near future.
I have some ideas on how to handle it but thats for later.
