Improve default text output of commands

[sdairs]

In cases where commands output information, we should use easier to parse structure.

For example, local server list

Servers:
  blue-bird [stopped]
  dark-bolt [stopped]
  dark-orca [stopped]
  dark-puma [stopped]
  dark-puma-2 [stopped]
  default [stopped]
  dev [stopped]
  fast-bolt [stopped]
  iron-orca [stopped]
  pale-crow [stopped]
  pale-gull [stopped]
  pale-newt [stopped]
  red-frog [stopped]
  slim-crow [stopped]
  test [stopped]
  wild-crow [stopped]

16 servers, 0 running
