cni_ds_init should not be pid1 of cni daemon pod

[Antoni Segura Puimedon]

In containerized CNI, the executable that docker/crio runs is cni_ds_init. cni_ds_init is a shell script that sets up the environment and finally either runs the daemon executable or sleeps, depending of whether the deployment calls for a CNI daemon or just an executable.

The problem with doing that is that the PID 1 will be the shell script that is not doing anything once it reaches the cni daemon executable or sleep. This means the reported main process for the container/pod will not be
the one doing the job.
