[FR] Allow API key override for initial user (or specify per user during scripted creation)

[weslambert]

Is your feature request related to a problem? Please describe. There is currently no way to obtain an API key for the initial user, unless logged in via the web interface.

Describe the solution you'd like I would like to be able to specify my own API key or override the default API key generation (similar to how this is done with the administrator account and it's password) so that the API key can be obtained and used for interacting with the API and bootstrapping the environment before users log into the web interface.

Describe alternatives you've considered I've considered querying the local Postgres database, although this is messy and not a great practice, in general.
