feature request - launch browser to allow admin to complete mfa to streamline connection add

[lenoretumey]

during admin connection add/save, frodo should launch a browser to allow the admin to complete MFA, and then create a service account with proper scopes along with a log API key/secret which could then be used in subsequent calls. This would streamline what is currently a manual process of creating the service account & API keys via the Admin UI & then specifying them in a connection add command line.
