Allow STS credentials instead of username/password

[jamie-pate]

Description

When working with terraform it's best practice to generate temporary credentials instead of username/password or other long term credentials.

This is possible with the minio AssumeRoleWithWebIdentity api using this example but it doesn't seem like this provider supports the username+secret+token authentication parameters that would make it work.

Steps to Reproduce

1. Set up the example to obtain AccessKeyId,SecretAccessKey,SessionToken from the AssumeRoleWithWebIdentity api.
2. Obtain these credentials
3. Try to put them into the provider as $MINIO_USERNAME and $MINIO_PASSWORD but there's no way to do that.

Expected behavior: [What you expect to happen]
Ideally there would be a third $MINIO_SESSION_TOKEN parameter. (minio_session_token in the provider config) that would allow these credentials to work using STS

Actual behavior: [What actually happens]
There doesn't appear to be a way to enter the session token

Reproduces how often: [What percentage of the time does it reproduce?]
100%
