I am not sure if we should keep the page_cycler_v2 branding. I am thinking about
naming this "loading.mobile" to make it clearer for people who are new to our
benchmarks system.

Wdyt?

Let's move this to tools/perf/benchmarks/loading.py and name it "loading.mobile"

Done.
Is it OK that loading.LoadingMobile inherits page_cycler_v2.PageCyclerV2?
