Wire network interface into libpod

Make use of the new network interface in libpod.

This commit contains several breaking changes:
- podman network create only outputs the new network name and not file
  path.
- podman network ls shows the network driver instead of the cni version
  and plugins.
- podman network inspect outputs the new network struct and not the cni
  conflist.
- The bindings and libpod api endpoints have been changed to use the new
  network structure.

The container network status is stored in a new field in the state. The
status should be received with the new `c.getNetworkStatus`. This will
migrate the old status to the new format. Therefore old containers should
contine to work correctly in all cases even when network connect/
disconnect is used.

New features:
- podman network reload keeps the ip and mac for more than one network.
- podman container restore keeps the ip and mac for more than one
  network.
- The network create compat endpoint can now use more than one ipam
  config.

The man pages and the swagger doc are updated to reflect the latest
changes.
