Finer latency histogram buckets

The request latency histograms http_requests_duration_seconds and http_response_time_seconds (ory_oathkeeper_requests_duration_seconds and ory_oathkeeper_response_time_seconds in Ory Oathkeeper) now use boundaries chosen for request latency: 10 ms, 25 ms, 50 ms, 100 ms, then every 100 ms to 500 ms, 750 ms, 1 s, 1.5 s, 2 s, 3 s, 5 s, 10 s and 20 s.

Percentiles computed with histogram_quantile over a window that spans the upgrade mix both layouts and read wrong until the window has moved past it. Update dashboards and alerts that match on specific le values to the new boundaries.
