Disk cache: Set up an experiment to measure the effect of

increasing the maximum cache size.

There will be three groups on the experiment, each group with
10% of the users (Dev Channel). Each group will have the max
cache size increased by a factor from 2 to 4 times the current
size, and we'll measure the age of evicted entries.

I'm also adding a few metrics of reliability, to detect how
often we're not getting to do proper cleanup.
