Allow selection of API endpoint
API commands are routed to an automatically selected endpoint. Resource queries report state cached in the region hosting that endpoint. The cache can be stale and omit resources created indirectly in a different region by an immediately preceding API call. E.g., the resources in the managed resource group of a new AKS cluster.
The ability to direct the query to the region containing the resources would avoid the need to wait for the resources to appear in the cache.
