Wifi Metrics STA event list

Browse Source 
Implemented a new, more atomic connection event list for tracking wifi
connection event metrics. The old 'packaged' connection events are too
inflexible/artificial, and only track the connection ATTEMPT.
The new event list will track the individual commands/messages/events
modifying the state of wifi, with the post processing to determine
number of connections, successes, failures, etc, offloaded to the
consumer of the data.
Coverage has also been extended to track the full connection from
initiation, to connection and final disconnection, as well as piping
through of specific disconnection status and reason codes.
