A user destroying a HostedCluster can cause the HostedCluster to hang indefinitely if the destroy command times out during execution

This is due to the hcp cli placing a finalizer on the HostedCluster during deletion which the cli tool later removes after waiting for some clean up actions to occur. If a user cancels the `hcp destroy cluster` command (or the command times out) while the cli is waiting for cleanup, then the HostedCluster will hang indefinitely with a DeletionTimestamp != nil.

The cli tool should not be putting the HostedCluster into an un-reconcilable state. All this finializer cleanup logic belongs on the backend.
