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.

Add an image label (e.g. label=value) to the image metadata. Can be used multiple times.

Users can set a special LABEL io.containers.capabilities=CAP1,CAP2,CAP3 in a Containerfile that specifies the list of Linux capabilities required for the container to run properly. This label specified in a container image tells Podman to run the container with just these capabilities. Podman launches the container with just the specified capabilities, as long as this list of capabilities is a subset of the default list.

If the specified capabilities are not in the default set, Podman prints an error message and runs the container with the default capabilities.
