Feature request: Add completions

[b0o]

Completions would be a very nice addition to this plugin!

Alternatively, if fuzzy-sys arguments were made to be compatible with systemctl (e.g. start rather than --start), you could piggyback on the existing systemctl completions with compdef fuzzy-sys=systemctl.

Good idea! Feel free to make a pull request, if not, I will try to put some work towards this in a few weeks :slightly_smiling_face:.

Edit: Haven't had time to do this, if anyone is willing, feel free to submit a PR
