k8s host empty-dir is equivalent to docker volumes.
For this case, we should just use the host directory even
for system directories.
Move the isEphemeral function to virtcontainers to not
introduce cyclic dependency.

We were considering all empty-dir k8s volumes as backed by tmpfs.
However they can be backed by a host directory as well.
Pass those as 9p volumes, while tmpfs volumes are handled as before,
namely creating a tmpfs directory inside the guest.
The only way to detect "Memory" empty-dirs is to actually check if the
volume is mounted as a tmpfs mount, since any information of k8s
"medium" is lost at the OCI layer.

Refactor the config related codes into a separated
package which can be shared with other cli programs
such as kata's shimv2.
