Chris Lu 2c2df751f5 Perf CI: benchmark the Rust volume server and report memory usage (#10111) ...

* ci: add per-process memory sampler for perf jobs

Samples VmRSS once a second into a CSV and records peak VmHWM per process
on stop. Linux only; reads /proc/<pid>/status.

* ci: run perf benchmarks on the Rust volume server and report memory

Matrix the throughput and S3 jobs over go/rust volume servers, using a
standalone master (plus filer for S3) and swapping only the volume binary
so the two are directly comparable. Sample peak RSS in every job and surface
it per impl in the run summary.

* ci: harden mem sampler arg handling and peak fallback

Guard against missing args under set -u, and fall back to the max RSS
sampled when a process exits before VmHWM can be read.
