Feature request: Support programmatic custom role creation via REST API and Terraform.

Goal:

Our platform team wants to build self-service platform for Fivetran. Teams make own RBAC, connectors, destinations. Need tight RBAC per team per destination so teams not step on each other.

Blocker:

Current Fivetran API and Terraform does not support custom role creation. Can only click in UI by hand. Cannot automate per-team destination roles.
