When we parse isolation we expect users to input chroot, oci, rootless.
So when we translate the constants back to strings, we should use the
same values.
These human names need to be passed over the podman-remote build
bindings, so we need to make them match.
Also docker describes an isolation of "default", which we should also
handle for potential scripts.

We want to shrink the size of the import when importing pkg from
buildah. This should help us shrink the size of the golang bindings
in podman.
