The performance issue in #19467 drove me to add a benchmark for
system-df to avoid regressing on it in the future.
Comparing current HEAD to v4.6.0 yields
```
/home/vrothberg/containers/podman/bin/podman system df ran
201.47 times faster than /usr/bin/podman system df
```

Create the containers with a custom network. It has an impact on the
speed of container creation.

Add a script with reproducers for bugzilla.redhat.com/show_bug.cgi?id=2162111.
The results are not much different compared to the already existing
scripts. Podman is faster despite for container removal.

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`)
