You can put any given process is a cgroup. It doesn't have to be a container.

If you have a statically linked executable, setup the cgroup for it as you will. No containers needed. You can namespace is as well.

No `FROM X` `RUN Y` dockerfile stuff needed.

Yes, I run many programs inside cgroups, but not in containers.

Yes.

Yes. dockerfile only sets up the chroot in an overlayfs and fires up the "container" using mechanisms present in the kernel already.
