Manager: Add equivalent AMI actions for the bridge CLI commands.

Adds the following AMI events, closely following their CLI counterparts:

BridgeDestroy
BridgeKick
BridgeTechnologyList
BridgeTechnologySuspend
BridgeTechnologyUnsuspend

BridgeDestroy kicks an entire bridge, where BridgeKick kicks just one
channel off the bridge. When kicking a channel, specifying the bridge
also (optional) insures it is not removed from the wrong bridge.  The
BridgeTechnology events allow viewing and changing suspension status,
which affects only subsequent not active bridging.
