add container-init support
Add support for executing an init binary as PID 1 in a container to forward signals and reap processes. When the `--init` flag is set for podman-create or podman-run, the init binary is bind-mounted to `/dev/init` in the container and "/dev/init --" is prepended to the container's command. The default base path of the container-init binary is `/usr/libexec/podman` while the default binary is catatonit [1]. This default can be changed permanently via the `init_path` field in the `libpod.conf` configuration file (which is recommended for packaging) or temporarily via the `--init-path` flag of podman-create and podman-run. [1] https://github.com/openSUSE/catatonit Fixes: #1670 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
