OAM operations 1 - miscellaneous

OAM operations changes are large, need to break down to multiple
submissions based on size and compilability. This is the first set which
covers: feature installation, audit log message, listener instantiation
and etc.

Includes these user stories: APPC-39/41/43/44/45/46/52/77.
