Implement Terminate operation in DCM

Also makes minor changes to non-terminate code as a side-effect of
supporting the new Terminate operation (such as including tagContext in
the LogicalCloudClient implementation of LogicalCloudManager interface).
These changes are/will also be leveraged by other operations.
