[APPC-44] APPC Lifecycle Management refactor
Pull APPC lifecycle Management out of APPC dispatcher, so that it can be used by both APPC dispatcher and APPC OAM. This is the pre-step of introducing APPC OAM operations. Issue-Id: APPC-44 Change-Id: Icbde399b5121fae9e1919cfdd5c77bbe55d61188 Signed-off-by: beili.zhou <beili.zhou@amdocs.com>
