Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.
Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.

Updated the logic to handle if extra args are passed with existing hyphens in the arg. The test was updated to add the additional case of having pre-existing hyphens. The method name was also refactored based on previous feedback.

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".

The kube-apiserver cert should have the same SANs in the same order,
excluding the extra user-configured SANs since this will only be used
in-cluster.

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.

As per documentation, the cloud-provider flag should not be passed to
controller-manager when using cloud-controller. However, the legacy
cloud-related controllers still need to be explicitly disabled to
prevent errors from being logged.
Fixing this also prevents controller-manager from creating the
cloud-controller-manager service account that needed extra RBAC.

Resolves warning 2 from #2471.
As per https://github.com/kubernetes/cloud-provider/issues/12 the
ClusterID requirement was never really followed through on, so the
flag is probably going to be removed in the future.
One side-effect of this is that the core k8s cloud-controller-manager
also wants to watch nodes, and needs RBAC to do so.

Since we're replacing the k3s rolebindings.yaml in rke2, we should allow
renaming this so that we can use the white-labeled name downstream.

Before this change, k3s configured the scheduler and controller's
insecure ports to listen on 0.0.0.0. Those ports include pprof, which
provides a DoS vector at the very least.
These ports are only enabled for componentstatus checks in the first
place, and componentstatus is hardcoded to only do the check on
localhost anyway (see
https://github.com/kubernetes/kubernetes/blob/v1.18.2/pkg/registry/core/rest/storage_core.go#L341-L344),
so there shouldn't be any downside to switching them to listen only on
localhost.
