Jan Kaluza 7612af4c0e Rewrite the Quadlet documentation
This commit does the following:

- Splits the podman-systemd.unit.5.md into multiple files - one for each quadlet file type.
- Adds the podman-quadlet-basic-usage.7.md for quadlet examples.
- Majority of the text in the new files is copied from the podman-systemd.unit.5.md
- Adds support for very simple condditional in the markdown_preprocess.
- Uses new logic in markdown_preprocess in options/*.md to use a single .md file for both
  podman subcommands man-pages and quadlet man-pages. This deduplicates the Quadlet man-pages a lot.
- Adds new `@@option quadlet:source.md`` preprocess command to import such .md files from options directory.

Memory limit. A _unit_ can be **b** (bytes), **k** (kibibytes), **m** (mebibytes), or **g** (gibibytes).
Allows the memory available to a container to be constrained. If the host
supports swap memory, then the << '**Memory=**' if is_quadlet else '**--memory**' >> memory setting can be larger than physical
RAM. If a limit of 0 is specified (not using << '**Memory=**' if is_quadlet else '**--memory**' >>), the container's memory is
not limited. The actual limit may be rounded up to a multiple of the operating
system's page size (the value is very large, that's millions of trillions).
This option is not supported on cgroups V1 rootless systems.
