Lightweight checkin output for network stats.
Define and print a compact version of network statistics when dump
is requested with the "--checkin" flag. Defaults to last 24 hours,
but included data can be tweaked with various flags.
Groups together detailed network identities into larger umbrella
terms like "mobile" and "wifi."
