a84c75af62 Adds a command-line flag '--disable-helm-controller' that will disable
the server's built-in helm controller.

Problem:
Testing installation and uninstallation of the Helm Controller on k3s is
not possible if the Helm Controller is baked into the k3s server.

Solution:
The Helm Controller can optionally be disabled, which will allow users
to manage its installation manually.

e77fd18270 Sign CSRs for kubelet-serving with the server CA
Problem:
Only the client CA is passed to the kube-controller-manager and
therefore CSRs with the signer name "kubernetes.io/kubelet-serving" are
signed with the client CA. Serving certificates must be signed with the
server CA otherwise e.g. "kubectl logs" fails with the error message
"x509: certificate signed by unknown authority".

Solution:
Instead of providing only one CA via the kube-controller-manager
parameter "--cluster-signing-cert-file", the corresponding CA for every
signer is set with the parameters
"--cluster-signing-kube-apiserver-client-cert-file",
"--cluster-signing-kubelet-client-cert-file",
"--cluster-signing-kubelet-serving-cert-file", and
"--cluster-signing-legacy-unknown-cert-file".

6e8284e3d4 rootless: enable resource limitation (requires cgroup v2, systemd)
Now rootless mode can be used with cgroup v2 resource limitations.
A pod is executed in a cgroup like "/user.slice/user-1001.slice/user@1001.service/k3s-rootless.service/kubepods/podd0eb6921-c81a-4214-b36c-d3b9bb212fac/63b5a253a1fd4627da16bfce9bec58d72144cf30fe833e0ca9a6d60ebf837475".

This is accomplished by running `kubelet` in a cgroup namespace, and enabling `cgroupfs` driver for the cgroup hierarchy delegated by systemd.

To enable cgroup v2 resource limitation, `k3s server --rootless` needs to be launched as `systemctl --user` service.
Please see the comment lines in `k3s-rootless.service` for the usage.

Running `k3s server --rootless` via a terminal is not supported.
When it really needs to be launched via a terminal, `systemd-run --user -p Delegate --tty` needs to be prepended to create a systemd scope.

c5aad1b5ed Disable the ServiceAccountIssuerDiscovery feature-gate.
We're not setting ``--service-account-issuer` to a https URL, which causes an
error message at startup when the feature gate is enabled. From the
docs on that flag:

> If this option is not a valid URI per the OpenID Discovery 1.0 spec, the
> ServiceAccountIssuerDiscovery feature will remain disabled, even if the
> feature gate is set to true. It is highly recommended that this value
> comply with the OpenID spec:
> https://openid.net/specs/openid-connect-discovery-1_0.html. In practice,
> this means that service-account-issuer must be an https URL. It is also
> highly recommended that this URL be capable of serving OpenID discovery
> documents at {service-account-issuer}/.well-known/openid-configuration.
