Benchmark performance of Incus
This tool lets you benchmark various actions on a local Incus daemon.
It can be used just to check how fast a given host is, to
compare performance on different servers or for performance tracking
when doing changes to the codebase.
A CSV report can be produced to be consumed by graphing software.
