10-kuryr.conflist file from the template file kuryr.conflist.template
1. Currently kubelet's cni config file uses 10-kuryr.conf in kuryr. The
kubernetes can support the config file with two suffixes, ".conf" and
".conflist", the latter can be a list containing multiple cni plugins.
So I want to update the 10-kuryr.conf to 10-kuryr.conflist to satisfy
the need to use multiple plug-in support.
2. If I install the kuryr-cni by pod, the 10-kuryr.conf will only be
copied and overwrited from the kuryr/cni image container. What I
expected is we can customize the config file more freely. So I think we
can add an other file kuryr.conflist.template as the template, then we
generate the 10-kuryr.conflist fron it.
