The first one being RecommendedPluginOrder the second one being DefaultOffPlugins.
In case a cluster-admin did not provide plugin names they will be derived from these fields.

Handle failure cases on startup gracefully to avoid causing cascading
errors and poor initialization in other components. Initial errors from
config load cause the initializer to pause and hold requests. Return
typed errors to better communicate failures to clients.
Add code to handle two specific cases - admin wants to bypass
initialization defaulting, and mirror pods (which want to bypass
initialization because the kubelet owns their lifecycle).

Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.

lifecycle plugin: make use of the libraries under k8s.io/client-go/pkg/api and k8s.io/client-go/kubernetes
for the client libraries instead of k8s.io/kubernetes/client/*
move registration to AdmissionOptions

ApplyTo adds the admission chain to the server configuration the method lazily initializes a generic plugin
that is appended to the list of pluginInitializers.
apiserver.Config will hold an instance of SharedInformerFactory to ensure we only have once instance.
The field will be initialized in apisever.SecureServingOptions

In the long term AdmissionOptions will accepts various dependencies
and spit out AdmissionControl
