If we call Container(), we expect the namespace to be prefixed with "container:".
Add this check, and refactor to use named const strings instead of string literals

allow a container to run in a new cgroup namespace.
When running in a new cgroup namespace, the current cgroup appears to
be the root, so that there is no way for the container to access
cgroups outside of its own subtree.
By default it uses --cgroup=host to keep the previous behavior.
To create a new namespace, --cgroup=private must be provided.

it creates a namespace where the current UID:GID on the host is mapped
to the same UID:GID in the container.

We accidentally patched this out trying to enable ns:/path/to/ns
This should restore the ability to configure nondefault CNI
networks with Podman, by ensuring that they request creation of a
network namespace.
Completely remove the WithNetNS() call when we do use an explicit
namespace from a path. We use that call to indicate that a netns
is going to be created - there should not be any question about
whether it actually does.

We should be sharing cgroups namespace by default in pods
uts namespace sharing was broken in pods.
Create a new libpod/pkg/namespaces for handling of namespace fields
in containers
