As of MS1, delete-instance and delete-local-instance are implemented as synonyms.
This issue is to confirm whether or not this is the right behavior and once it
is decided what the right behavior is, implement it.
Proposal 1: leave it as it is. delete-instance and delete-local-instance do the
same thing when the identified instance is on the local host. If you run
delete-instance on an instance that is not local, it fails.
Proposal 2 (from Bill):
I expected delete-local-instance to work like create-local-instance -
do the local filesystem part and contact the DAS to do the config part.
Similarly, delete-instance would be like create-instance - a remote
command that asks DAS to do the config part and (eventually) contact
the remote node to do the filesystem part.
Here "eventually" would be via the ssh feature that will be provided later.
