More information on Delete Workspace dialog

When deleting a Workspace, it would be good to show:

• A list of VMs that will be deleted with usernames of who created them.
• The number of Notebooks in the Workspace.
• The number of Data Tables in the Workspace
• The 3-5 most recently edited Notebooks with their names.

We had a recent incident where someone deleted a workspace that was in use by others because the owner thought it was only theirs.
