* Disable helm CRD installation for disable-helm-controller
The NewContext package requires config as input which would
require all third-party callers to update when the new go module
is published.
This change only affects the behaviour of installation of helm
CRDs. Existing helm crds installed in a cluster would not be removed
when disable-helm-controller flag is set on the server.

Several places in the code used a 5-second retry loop to wait on
Runtime.Core to be set. This caused a race condition where OnChange
handlers could be added after the Wrangler shared informers were already
started. When this happened, the handlers were never called because the
shared informers they relied upon were not started.
Fix that by requiring anything that waits on Runtime.Core to run from a
cluster controller startup hook that is guaranteed to be called before
the shared informers are started, instead of just firing it off in a
goroutine that retries until it is set.

Fixes an issue where CRDs were being created without schema, allowing
resources with invalid content to be created, later stalling the
controller ListWatch event channel when the invalid resources could not
be deserialized.
This also requires moving Addon GVK tracking from a status field to
an annotation, as the GroupVersionKind type has special handling
internal to Kubernetes that prevents it from being serialized to the CRD
when schema validation is enabled.

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.

stream, if it comes in the same packet as the CONNECT header. These
