Request: Configure from a file and/or environment variables

[kief]

Howdy!

Two use cases for this request:

• I want to use oktaauth with more than one app (e.g. multiple AWS accounts)
• I have an app with multiple users (e.g. an AWS account for infrastructure training), and I want to make it easier for them to use oktaauth.

Currently I need to either type the arguments on the command-line every time I run the tool (yeah, command history helps), or else write a separate wrapper shell script for each app.

I'd prefer an easier way to set the parameters so I can re-use them. Two ways that would be handy:

• A configuration file, probably directory-based. For example, if I have a file named .oktaauth in my current directory, parent of my current directory, or up the tree to my home directory, then it uses that.
• If I set environment variables, e.g. OKTA_USERNAME, OKTA_APP_ID, OKTA_SERVER, then oktaauth uses those.

My ideal would be for oktaauth to support both. So I think the conventional precedence would be: 1) command-line arguments 2) environment variable 3) configuration file. I guess it could also take a command-line argument that points to a particular file, and that would probably(?) come between 1 and 2?
