Easy login to AWS through the command-line.

The project assumes you have:

1. An IAM account and credentials present in your environment (e.g. ~/.aws/credentials)
2. Permissions for the IAM account to assume a given role
3. The name of the role you want to assume

With the above in place you can get temporary credentials and a web UI login link, granting you all of the powers of the assumed role by running:

$ awsrole MyRole
# Export following vars in your shell for API/CLI access:
    export AWS_ACCESS_KEY_ID=ASI...
    export AWS_SECRET_ACCESS_KEY=10q2I...
    export AWS_SESSION_TOKEN=Fwo......

## Login URL: https://signin.aws.amazon.com/federation?Action=login......

Clicking on/opening the URL in the browser will land you in a preauthenticated session. Copy/pasting the export commands in your shell would enable CLI utilities from using the role's credentials.

The temporary credentials would be valid for up to 12h (max and default value)
