Hub Class

A Hub is a special type of workspace that acts as a parent and resource container for lightweight child workspaces called projects. Resources like the hub's storage account, key vault, and container registry are shared by all child projects.

As a type of workspace, hub management is controlled by an MLClient's workspace operations.
