[PASSPOINT] Add metrics to determine deployment/avail of Passpoint

Browse Source 
Add metrics which will help determine Passpoint availability in the
wild. The metrics measure the percentage of time a Passpoint network
is visible to user - by collecting historgrams of observations per
scan result.
