Zsh completion

[metalefty]

Related to #583, but this is for zsh, I have developed a zsh completion for vm-bhyve.

https://gist.github.com/metalefty/a9516554cb4fbe4c3e92590eb4cdf3b8

I developed this for my own use but thought I'd share it if it helps someone else. It is still in development, but for the most part works well.

I will create a separate repo instead of gist and accept PRs if some people (10+) like it.

Added some screenshots.

Nice! Thanks this is awesome. I just added it as a plugin to oh-my-zsh.

Also. I have a feature request already : )
