sudo podman network create --subnet '172.25.0.0/24' mynetwork
sudo podman run -d --rm --name instance0 --network mynetwork --ip 172.25.0.200 image:version
Error: error running container create option: cannot set a static IP if joining additional CNI networks: invalid argument

When '--ip 172.25.0.200' is removed, it assigns next available IP from the subnet.

Hmmm. This ought to be possible, but we'll need to talk to the CNI folks to make sure it's supported now.

Allow --ip and --mac to be set when joining a CNI net
01ae532 
These only conflict when joining more than one network. We can
still set a single CNI network and set a static IP and/or static
MAC.

Fixes containers#4500
