Add network options to podman pod create

Enables most of the network-related functionality from
`podman run` in `podman pod create`. Custom CNI networks can be
specified, host networking is supported, DNS options can be
configured.

Also enables host networking in `podman play kube`.

Fixes #2808
Fixes #3837
Fixes #4432
Fixes #4718
Fixes #4770
