API function to create/list/delete API Keys

[evilmog]

I'm going to be creating a temporary API Key generator for my users to tie into our other access granting pipelines. Is it possible to get new API functions to manage API keys?

At a minimum I would like to:

1. List api keys, and their associated user just like the webui
2. Create new api keys, attached to a specific user and have associated start and end dates just like the webui
3. remove an api key

Bonus feature: edit an existing API key
