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. Issue-ID: MULTICLOUD-1143 Change-Id: Idbd2ec9f6cf0e5584a0f51cf4c16144db56d9fa0 Signed-off-by: Igor D.C <igor.duarte.cardoso@intel.com>
