shill: Keeps track of successful wifi connection frequencies.
Saves the connection frequencies (and counts therefor) in the default
profile. Sends number of frequencies on which successful connections
have been made to an UMA stat.
BUG=chromium:222081
TEST=unittests and manual (look for UMA stat
'Network.Shill.Wifi.FrequenciesConnectedEver', disconnect from
wifi, reconnect, verify that the UMA stat went up by 1).
