def reason_message(version)
  "Replacing mod #{@current.name} because #{version} is different in Terrafile and Terrafile.lock"
end

#run ⇒ Object

Tricky logic, maybe spec this.

no mods specified:
  terraspace bundle update  # no mods specified => update all
  terraspace bundle install # no Terrafile.lock => update all
mods specified:
  terraspace bundle update s3  # explicit mod => update s3
  terraspace bundle install s3 # errors: not possible to specify module for install command

Note: Install with specific mods wipes existing mods. Not worth it to support.
