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.

Allows a transformer (such as an encrypter) to force an update if a new
key is in use, thus allowing simple writes to the REST layer to
trivially migrate keys.
This adds a new value transformer to the etcd2 store that can transform
the value from etcd on read and write. This will allow the store to
implement encryption at rest or otherwise transform the value prior to
persistence.
