Paul Holzinger f441190d10 Allow multiple --network flags for podman run/create
We allow a container to be connected to several cni networks
but only if they are listed comma sperated. This is not intuitive
for users especially since the flag parsing allows multiple string
flags but only would take the last value. see: spf13/pflag#72

Also get rid of the extra parsing logic for pods. The invalid options
are already handled by `pkg/specgen`.

A test is added to prevent a future regression.
