SimpleCache on ChromeOS (changing HTTP cache backend)

Project Member Reported by kenjibaheux@chromium.org, May 13 2016

Issue description

We currently have 2 HTTP cache backend (i.e. SimpleCache on Android, BlockFile on desktop platforms). This is unfortunate and hinders our velocity (separate optimizations, complexity).

Let's try to fix this by settling down on SimpleCache.
OS specific issues because performance and therefore launch criteria will vary across platforms.

Beta experiment takeaway: metrics look good => let's try Stable per the plan.

The following revision refers to this bug:

Make SimpleCache the default backend on ChromeOS/Linux.

The current beta on these platforms is looking good, so we will
launch. However, validating simple cache in stable will take some
time. Thus, I'm switching the default to launch, but leaving us with
the finch trial so we can claw back users if we run into unexpected
trouble.

In the m53 timeframe, we'll just switch to the new default.
