'snap remove' output cleanup

[Mark Shuttleworth]

I currently see this:

  $ snap remove hello-world

  Done

Could we change it to list the actions undertaken?

  $ snap remove hello-world krita
  hello-world@frank removed
  krita (beta) removed

I dropped the blank line. Any errors would show up inline:

  $ snap remove hello-world fancy krita
  hello-world@frank removed
  fancy not installed
  krita (beta) removed

Thanks!

This got much better in snapd 2.18:

$ snap remove go-example-webserver hello-world
go-example-webserver removed
hello-world not installed

However the channel output is missing currently.
