want sdcadm delete #108
Description
When creating additional services like papi, workflow, portolan, etc, sdcadm create workflow -s <UUID> is used to create an instance. If you create a 2nd and third instance, then migrate to new secondary headnodes, create a 4th and 5th instanecs, then decommission the old compute nodes, the instances remain orphaned in sapi. If by chance you subsequently run sdcadm experimental fix-core-resolvers the command fails with non-existent instances. You then must manually delete the instances from sapi with sdc-sapi /instances/<MISSING_VM_UUID> -X DELETE in order to get rid of the non-existent instance to get the resolvers to properly fix. sdcadm delete workflow1 and sdcadm delete workflow2 ideally should remove the instances from sapi in their entirety so that sdc is not left with orphaned core instances. Alternatively an sdcadm clean command could also be an ideal command to remove all orphaned instances from sapi as well.
