cephfs-tool covers data-plane I/O, but MDS journaler/throttle stalls and
Init CLIENT_CAPS storms need a client-side metadata hammer with a fixed
nested tree, weighted Run mixes, and multi-process coordination. Without
that, regression and performance work depends on ad-hoc scripts or
proprietary suites.
Add cephfs-mdsbench (libcephfs): per-client CL{id}_MDSBENCH trees, balanced/
journal-heavy/lookup-heavy mixes, rate limiting, Init populate with optional
cap-storm, ready-file start barrier, progress/JSON output, CMake install,
and CephFS docs using generic software-build style wording.
