Split ram and disk cache hit response times into separate metrics


Original description
by Stephen Bisordi from Yahoo

It appears that the response time for ram cache hits and disk cache hits is captured as a single metric
(transaction_totaltime.hit_fresh).  Would it be possible to split this into two separate metrics, or to add a ram cache
hit result code to the log to differentiate between ram and disk hits (similar to Squid's TCP_MEM_HIT)?

This change would allow for quicker troubleshooting of certain issues such as poor disk performance.
