Christian Schwarz 5385791ca6 add pageserver component-level benchmark (pagebench) (#6174)
This PR adds a component-level benchmarking utility for pageserver.
Its name is `pagebench`.

The problem solved by `pagebench` is that we want to put Pageserver
under high load.

This isn't easily achieved with `pgbench` because it needs to go through
a compute, which has signficant performance overhead compared to
accessing Pageserver directly.

Further, compute has its own performance optimizations (most
importantly: caches). Instead of designing a compute-facing workload
that defeats those internal optimizations, `pagebench` simply bypasses
them by accessing pageserver directly.

Supported benchmarks:

* getpage@latest_lsn
* basebackup
* triggering logical size calculation

This code has no automated users yet.
A performance regression test for getpage@latest_lsn will be added in a
later PR.
