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.
