Provide an option to specify creation of a new instance upon deployment

[Robert Ayres]

Currently, if you destroy a deployed service, the machine instance is re-used when deploying a new charm. It'd be great if you could specify via a flag, maybe '--new-instance', that a new instance should be created and used for this deployment. This is particularly useful if you destroy a service but want to keep the instance dormant in the background for further tasks, e.g. data retrieval.

Great idea Robert. I think the workaround right now is just to deploy something non-destructive to any instances you want to keep around, like a "null" charm or something.

i think we need to stop reusing machines, and add a separate add-machine to account for this case.
