7464007037 Store extra metadata and cluster ID for snapshots
Write the extra metadata both locally and to S3. These files are placed such that they will not be used by older versions of K3s that do not make use of them.

Add --image-service-endpoint flag (#8279)
* Add --image-service-endpoint flag

Problem:
External container runtime can be set but image service endpoint is unchanged
and also is not exposed as a flag. This is useful for using containerd
snapshotters outside of the ones that have built-in support like
stargz-snapshotter.

Solution:
Add a flag --image-service-endpoint and also default image service endpoint to
container runtime endpoint if set.

45d8c1a1a2 Soft-fail on node password verification if the secret cannot be created
Allows nodes to join the cluster during a webhook outage. This also
enhances auditability by creating Kubernetes events for the deferred

992e64993d Add support for kubeadm token and client certificate auth
Allow bootstrapping with kubeadm bootstrap token strings or existing
Kubelet certs. This allows agents to join the cluster using kubeadm
bootstrap tokens, as created with the `k3s token create` command.

When the token expires or is deleted, agents can successfully restart by
authenticating with their kubelet certificate via node authentication.
If the token is gone and the node is deleted from the cluster, node auth
will fail and they will be prevented from rejoining the cluster until
provided with a valid token.

Servers still must be bootstrapped with the static cluster token, as
they will need to know it to decrypt the bootstrap data.

c0045f415b agent(netpol): Explicitly enable IPv4 when necessary
Before this change, kube-router was always assuming that IPv4 is
enabled, which is not the case in IPv6-only clusters. To enable network
policies in IPv6-only, we need to explicitly let kube-router know when
to disable IPv4.

b6e71ef990 Added support for repeated extra arguments
Problem:
Specifying extra arguments for the API server for example is not supported as
the arguments get stored in a map before being passed to the API server.

Solution:
Updated the GetArgs function to store the arguments in a map that can have
multiple values. Some more logic is added so that repeated extra arguments
retain their order when sorted whilst overall the arguments can still be
sorted for improved readability when logged.

Support has been added for prefixing and suffixing default argument values
by using -= and += when specifying extra arguments.
