Read credentials from a file

[eruvanos]

Hi, our organisation just changed the access to CF and restricted CI/CD pipelines to use temporary cf users.

We are able to retrieve them in a task, but do not see a way to fill them back into the cf-resource.

It would be nice, if we could provide the credentials or config.json from outside. This may also help others, that are limited to multi factor authentication using cf login --sso.

What do you think?
