[ledger][benchmarks] Add benchmark for page pre-caching.

Test: Check output of add_new_page_precached.tspec benchmark
Bug: LE-617

Once LevelDb instances are pre-cached, Ledger::GetPage will have
an improved perforance when requesting new pages, with sufficient
time gap between two requests.

This CL adds a new benchmark to capture that improvement once LE-617
is done. Before that, the results of add_new_page_precached
benchmark are expected to be similar to those of add_new_page.

Peridot

Peridot is a framework for composed, intelligent and distributed user experiences.

Applications not explicitly designed to interoperate (and possibly implemented in different programming languages) are ephemerally downloaded and dynamically composed to run in a shared context. The framework manages application lifecycle, resources and view hierarchy; and well as context and suggestion infrastructure.

State of Peridot experiences is transparently synchronized across user devices using a distributed offline-first storage system.
