Add a set of scripts using hyperfine for comparing two container engines. I am currently using the scripts for comparing Podman and Docker, and with older versions of Podman. These scripts are not meant for production usage but to aid in tracking down performance regressions and bottlenecks. Run the scripts via `sudo sh $script.sh`. Use the following environment variables to change the default behavior: * `ENGINE_A` to set container engine A (default `/usr/bin/podman`) * `ENGINE_B` to set container engine B (default `/usr/bin/docker`) * `RUNS` to change the runs/repetitions of each benchmarks (default `100`) * `NUM_CONTAINERS` to change the number of created containers for some benchmarks (e.g., `ps`) (default `100`) * `IMAGE` to change the default container image (default `docker.io/library/alpine:latest`) Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
