OAM operations 2 - oam
OAM operations changes are large, need to break down to multiple submissions based on size and compilability. This is the second set which covers the following OAM operations: start, stop, restart, maintenance-mode, and timeout of the operation along with error OAM state. Includes these user stories: APPC-39/41/43/44/45/46/52/77. Issue Id: APPC-38 Change-Id: Iafad643c5ba2d2af24482b03db8f7a40397fa46e Signed-off-by: beili.zhou <beili.zhou@amdocs.com>
