support multiple source profiles

[karlderkaefer]

The source profile name is configured only once for all profiles

source: suite
destination: suite-mfa

But we also want to support that you can configure different source profiles for same account and cluster. This is useful when you want to authenticate as different kubernetes user in same cluster.

It is supported with --config key, so you can specify path for alternative profiles like

aws-mfa-config --config ~/.aws-mfa-profile1.yaml
