Add container name to hosts entry when using syntax --network container:name

[skorhone]

/kind feature

Description
When referencing another container with podman run --network container:name, podman creates a host entry that contains referenced containers ip and id.

This requires user to do an additional step of resolving container id when running ad-hoc commands

podman run -it --network container:sonar_mysql -v ./sonar-dump.gz:/sonar-dump.gz --rm mysql:5.7 mysql -h<would be awesome, if I could use sonar_mysql here>

Describe the results you received:
Hosts file has target container ip and id

Describe the results you expected:
Hosts file has target container ip, id and name

The traditional way to handle this is to set the hostname. in the first container. Then you can reference it in the second container. I have a simple patch to do what you want, but I am worried about why this was not done before. I will open the PR to get comment and see if someone knows why this was not done in the past.
