// recordTimings records timing information for the given step in establishing
// a connection. It always records that the step happened, and it records the
// highest timing threshold exceeded by the step.  Thresholds are 1, 2, 4, 8,
// and 16 seconds.
//
// For example, if calling this with step = "DNSLookup" and duration = 2.5
// seconds, we will increment two gauges, "DNSLookup" and
// "DNSLookupOver2Sec".
//
// The stats are qualified by MasqueradeSet (if specified), otherwise they're
// qualified by host. For example, if the MasqueradeSet is "cloudflare", the
// above stats would be recorded as "DNSLookupTocloudflare" and
// "DNSLookupTocloudflareOver2Sec". If the MasqueradeSet is "" and the host is
// "localhost", the stats would be recorded as "DNSLookupTolocalhost" and
// "DNSLookupTolocalhostOver2Sec".
