Remove dependency on kubernetes

podman parse and attach were using a very small portion of the kubernetes code
but using it caused a signficant increase in binary size.

-// Nsenter is part of experimental support for running the kubelet

-// Nsenter requires:
-//
-// 1.  Docker >= 1.6 due to the dependency on the slave propagation mode
-//     of the bind-mount of the kubelet root directory in the container.
-//     Docker 1.5 used a private propagation mode for bind-mounts, so mounts
-//     performed in the host's mount namespace do not propagate out to the
-//     bind-mount in this docker version.
-// 2.  The host's root filesystem must be available at /rootfs
-// 3.  The nsenter binary must be on the Kubelet process' PATH in the container's
-//     filesystem.
-// 4.  The Kubelet process must have CAP_SYS_ADMIN (required by nsenter); at
-//     the present, this effectively means that the kubelet is running in a
-//     privileged container.
-// 5.  The volume path used by the Kubelet must be the same inside and outside
-//     the container and be writable by the container (to initialize volume)
-//     contents. TODO: remove this requirement.
-// 6.  The host image must have "mount", "findmnt", "umount", "stat", "touch",
-//     "mkdir", "ls", "sh" and "chmod" binaries in /bin, /usr/sbin, or /usr/bin
-// 7.  The host image should have systemd-run in /bin, /usr/sbin, or /usr/bin
-// For more information about mount propagation modes, see:
