Add Support for Azure and GCP

[hriebesehl]

Currently methods db.cluster.create_cluster(), db.cluster.edit_cluster(), db.instance_pool.create_instance_pool(), and db.instance_pool.edit_instance_pool() only support API calls to AWS-based databricks workspaces. I'd recommend adding azure_attributes and gcp_attributes as parameters to these functions to support API calls on all platforms.

edit: opened an issue on databricks-cli here

This package just wraps databricks-cli; you might be better off requesting there.

Apologies - will do.
