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.
