Add get_workspace_id to WorkspaceClient

[mgyucht]

Changes

There are times when it is especially useful to get the workspace ID for the current workspace client. Currently, the workspace ID for the current workspace is exposed as a header in the SCIM Me API call. We'll expose this through a get_workspace_id() method, caching the workspace ID for the lifetime of the client.

In the future, we may add a meta service for exposing information about the current account/workspace. At that point, we can migrate off of this somewhat hacky approach.

Ports databricks/databricks-sdk-go#808 to the Python SDK.

Tests

• make test run locally
