refactor: local and remote commands into route

[augustoccesar]

Both local and remote commands implementation were pretty much the same with a small variation to parameters of functions.

This unifies the implementation of them. With that, also changes so that local and remote are a subcommand of a new Linkup command called route.

So:

• linkup local <name> -> linkup route local <name>
• linkup remote <name> -> linkup route remote <name>

Also updated the feedback of the command to show which session is being updated and where the target lives for each of the updated services.

> linkup route local service_1

Session: happy-snake
  service_1  ->  http://localhost:9292/

Closes SHIP-2631, SHIP-2630
