Matthias Schneider 56a083c812 fixed panic in network_policy_controller
I have rebooted a newly created k3s etcd cluster and this panic was triggered:

    ```

Darren Shepherd 2f5ee914f9 Add supervisor port
In k3s today the kubernetes API and the /v1-k3s API are combined into
one http server.  In rke2 we are running unmodified, non-embedded Kubernetes
and as such it is preferred to run k8s and the /v1-k3s API on different
ports.  The /v1-k3s API port is called the SupervisorPort in the code.

To support this separation of ports a new shim was added on the client in
then pkg/agent/proxy package that will launch two load balancers instead
of just one load balancer.  One load balancer for 6443 and the other
for 9345 (which is the supervisor port).

Erik Wilson 5b98d10e4b Warn if NPC can't start rather than fatal error
If the ip_set kernel module is not available we should warn
that the network policy controller can not start rather than
cause a fatal error.

Also adds module probing and config checks for ip_set.

Brennan Ashton a952d5c32a Default device net config enables ip forwarding
The Linux kernel is inconsistent about how devconf is configured for new
network namespaces between ipv4 and ipv6. The behavior can also be
controlled via net.core.devconf_inherit_init_net in Linux 5.1+ so make
sure to enable forwarding on all and default for both ipv6 and ipv4.

This issue first came up testing on a yocto kernel that had this patch:
 ipv4: net namespace does not inherit network configurations

Jacob Blain Christen 063efb25bb Mutable --node-label values for server/agent sub-commands.
Values passed in via the server/agent `--node-label` flag are treated as mutable. They are passed through to the kubelet just as before but after the kubelet comes up they are applied again. This allows for passing labels a k3s start-time that may be necessary for scheduling but may change from boot to boot, e.g. `k3os.io/version` after an upgrade.

Tested locallon on my amd64 workstation with the docker container.

Addresses #1119.

Darren Shepherd ff34c5c5cf Download cert/key to agent with single HTTP request
Since generated cert/keys are stored locally, each server has a different
copy.  In a HA setup we need to ensure we download the cert and key from
the same server so we combined HTTP requests to do that.
