Feature/improve yubikey usage
Improve the usage of yubikey for other av commands
Hey @nbrys - thank you for proposing this contribution! The one issue with moving from an alias to a function is that we lose the default auto-completion behavior.
Before
Type avl + space and then press the Tab key. You'll see your profiles appear as autocomplete suggestions:

After
On this PR, since avl (and others) moved to a function, autocompletion of profiles no longer works.

(you'll see in the screenshot it's suggesting foo.txt, a file in the demo directory, not my aws-vault profiles).
Solution
I'm happy to accept a changeset, I just want to make sure that we don't lose the autocomplete functionality that existed before this change. @reegnz submitted a PR a while back that focused on improving autocomplete, which might be interesting to take a look at: https://github.com/blimmer/zsh-aws-vault/pull/21
