CodecFactory is started with EnableStrict that throws an error when deserializing
a Kubelet component config that is malformed (e.g. unknown or duplicate keys).
When strict decoding a v1beta1 config fails, non-strict decoding is used and a warning is emitted.
For this, NewSchemeAndCodecs is now a variadic function that can take multiple
arguments for augmenting the returned codec factory. Strict decoding is
then explicitely enabled when decoding a kubelet config.
Additionally, decoding a RemoteConfigSource needs to be non-strict
to avoid an accidental error when it contains newer API fields that are not
yet known to the Kubelet.
DecodeKubeletConfiguration returns a wrapped error instead of a simple string
so its type can be tested.

Add keys for test cases struct fields, remove nil field initialization

This reverts commit f4afdecef8, reversing
changes made to e633a1604f.
This also fixes a bug where Kubemark was still using the core api scheme
to manipulate the Kubelet's types, which was the cause of the initial
revert.
