Pass options to configured credential manager

[traeok]

Is your feature or enhancement request related to a problem or limitation? Please describe

Currently, there is no way to pass options to the configured credential manager. Credential managers would have to implement logic to detect environment variables and behave accordingly.

Describe your enhancement idea

Implement support for defining and passing options into the configured credential manager.

Describe alternatives you've considered

Using environment variables, but this feels unwieldy and involves adding documentation & raising awareness to the new options.

Provide any additional context

Pre-requisite for #2458
