fix play kube --network options
Commit 092902b45555 introduced advanced network options for podman play
kube. However this never worked because it unconditionally set the
network mode to bridge after it parsed the network option.
Added a test to ensure the correct mode is set.
Truly fixes #10807

The host and bridge network mode should be configured in the yaml file. +Valid _mode_ values are: + +- **none**: Create a network namespace for the container but do not configure network interfaces for it, thus the container has no network connectivity. +- **container:**_id_: Reuse another container's network stack. +- **network**: Connect to a user-defined network, multiple networks should be comma-separated. +- **ns:**_path_: Path to a network namespace to join. +- **private**: Create a new namespace for the container. This will use the **bridge** mode for rootfull containers and **slirp4netns** for rootless ones. +- **slirp4netns[:OPTIONS,...]**: use **slirp4netns**(1) to create a user network stack. This is the default for rootless containers. It is possible to specify these additional options: + - **allow_host_loopback=true|false**: Allow the slirp4netns to reach the host loopback IP (`10.0.2.2`, which is added to `/etc/hosts` as `host.containers.internal` for your convenience). Default is false. + - **mtu=MTU**: Specify the MTU to use for this network. (Default is `65520`). + - **cidr=CIDR**: Specify ip range to use for this network.

Default. + Note: Rootlesskit changes the source IP address of incoming packets to a IP address in the container network namespace, usually `10.0.2.100`. If your application requires the real source IP address, e.g. web server logs, use the slirp4netns port handler. The rootlesskit port handler is also used for rootless containers when connected to user-defined networks. + - **port_handler=slirp4netns**: Use the slirp4netns port forwarding, it is slower than rootlesskit but preserves the correct source IP address. This port handler cannot be used for user-defined networks. #### **--quiet**, **-q** |
