Docker compatibility: Container inspect endpoint returns null for NetworkSettings/Ports

[skorhone]

/kind bug

Description

Steps to reproduce the issue:

1. Create a container with published ports

2. Call docker compatible container inspect api endpoint

Describe the results you received:
Ports is returned as null. There is no code for mapping NetworkSettings

Describe the results you expected:
NetworkSettings is returned with published Ports. If random host port was requested (port was undefined), then ranomized port should be returned as HostPort

Additional information you deem important (e.g. issue happens only occasionally):

Output of podman version:

Version:      2.0.0
API Version:  1
Go Version:   go1.13.8
Built:        Thu Jan  1 02:00:00 1970
OS/Arch:      linux/amd64

I'll see, if I can setup a dev environment to create patch for this tomorrow. Not sure, if I'll find time to map all variables from NetworkSettings, but I'd recon that ports and ip are what most tool require.

Tested locally on Ubuntu 20.04 LTS
