Need to update AWS key used for Altus Director environments

[#1]

During an overly ambitious cleanup effort, the IAM user / access key used by our Altus Director server was deleted from AWS and now we can no longer manage our clusters.  I would like to either update the access key used by director, or remove the key and force director to rely on IAM role.  Please advise.

Solved:

The Altus Director web console provides a way to update an environment's provider credentials, but only after all clusters/deployments have been deleted.  To update the credentials for existing deployment, I had to use director's API:

/api/d6.2/environments/{name}/provider/credentials

"Update provider credentials for a specific environment"
