Jean Boussier 06d3b358df Replace allocations count by GC time in request logs
Allocations count is often an interesting proxy for performance,
but not necessarily the most relevant thing to include in request
logs, given they aren't a per thread metric, so the reporting
is widely innacurate in multi-threaded environments.

Since Ruby 3.1 there is now `GC.total_time` which is a monotonically
increasing counter of time spent in GC. It still isn't really a per
thread metric, but is is more interesting because it uses the same
unit as the response time, allowing to better see when you have a GC
pause performance issue.

= Action View

Action View is a framework for handling view template lookup and rendering, and provides
view helpers that assist when building HTML forms, Atom feeds and more.
Template formats that Action View handles are ERB (embedded Ruby, typically
used to inline short Ruby snippets inside HTML), and XML Builder.

You can read more about Action View in the {Action View Overview}[https://guides.rubyonrails.org/action_view_overview.html] guide.
