This change means, that docker-compose can now, like podman-compose containers/podman-compose#166, make use of the user namespaces features of podman.

For example, the following works when using rootless podman in combination with docker-compose:

version: "3.7"

services:
  postgres1:
    image: docker.io/postgres:bullseye
    container_name: postgres1
    userns_mode: keep-id

Relaxed checking of userns_mode

When using docker-compose in combination with rootless podman
containers it is desirable to use the keep-id user namespace mapping.
By lifting the restriction to 'host' the userns_mode config can now be
used with podman to supply the keep-id or more complex configurations.
