Environment variable support for SSO

[jjshoe]

Describe the feature

A lot of CLI configuration can be controlled via environment variables, but the SSO parameters are not available. Reference: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html

Use Case

If I can pass in configuration via env vars it makes it easier to automate writing out the credentials file. Expanded:

1. write a config
2. get credentials
3. write a config again

If I can set sso params as env vars, I can reduce it down to:

1. get credentials
2. write a config

Additionally this is useful in scenarios like:

• Read only file system
• ci/cd where you don't want to risk inclusion
