Add containerenv information to /run/.containerenv
We have been asked to leak some information into the container
to indicate:
* The name and id of the container
* The version of podman used to launch the container
* The image name and ID the container is based on.
* Whether the container engine is running in rootless mode.
Fixes: https://github.com/containers/podman/issues/6192

These include _/etc/hosts_, _/etc/hostname_, and _/etc/resolv.conf_ to manage networking. These will be based on the host's version of the files, though they can be customized with options (for example, **--dns** will override the host's DNS -servers in the created _resolv.conf_). Additionally, an empty file is created in -each container to indicate to programs they are running in a container.

Additionally, a container environment +file is created in each container to indicate to programs they are running in a +container. This file is located at _/run/.containerenv_. When using the +--privileged flag the .containerenv contains name/value pairs indicating the +container engine version, whether the engine is running in rootless mode, the +container name and id, as well as the image name and id that the container is based on. When running from a user defined network namespace, the _/etc/netns/NSNAME/resolv.conf_ will be used if it exists, otherwise _/etc/resolv.conf_ will be used. |
