Add capability to generate bearer token for use by external integration
If you want to build some external integration or have a bot post on on behalf of an account there's no way to get a bearer token except by stealing it from your browser session which is silly and also doesn't make the token easily identifiable in the list of Oauth tokens in the user account security panel of PleromaFE.
I'd like an OTP cli command and an API endpoint so we can integrate this into the FE. It would be great if we can specify a custom string to identify the application, too.
