shell-completion: propose templates for disable/[re]enable/[re]start
Templates can be [re]enabled, on their own if the have DefaultInstance set, and with an instance suffix in all cases. Propose just the template name ending in @, to underline the instance suffix may have to be appended. Likewise for start/restart. This means that sometimes superflous units that one will not really want to operate on will be proposed, but this seems better than proposing a very incomplete set of names. https://bugs.freedesktop.org/show_bug.cgi?id=66912
