There was recent changes to cri to bring in a Windows section containing a security context object to the pod config. Before this there was no way to specify a user for the pod sandbox container to run as. In addition, the security context is a field for field mirror of the Windows container version of it, so add the ability to specify a GMSA credential spec for the pod sandbox container as well.
