Delete Third-Party Connection

Disconnects the connection: its credentials are cleared and it leaves the tenant's slot, but the connection and everything attached to it stay, so reconnecting continues it. For document storage connections, pass permanent=true to remove the connection outright: its documents are detached and its client folder mappings are deleted. That is the deliberate way to move to a different account or provider. Either form is refused while the connection is still the tenant's active one.
