/usr/libexec/kubernetes/kubelet-plugins is a new path in Kube 1.8 (related to
flexvolumes) which should be persisted. Like /etc/cni and /opt/cni we also need
to arrange for this path to be valid in the host environment (since various
system containers will try and mount bind mount it).

Rework the kubelet.sh script by adding an explicit step which waits for the
configuration to be valid, either by finding appropriate metadata or by waiting
explicitly for kubelet.conf to be created (e.g. by kubeadm) before launching
kubelet. The previous construct was implicitly waiting for kubelet.conf to be
created since kubelet fails if that file is not present.
Pull the set of start of day yaml files to be applied (currently just weave)
out of the kubelet image and into the LinuxKit yaml by providing a directory
which is searched for *.yaml after init.

With the master tailoring for docker now being in docker-master.yml,
kube-master and kube-node are identical, so just use a single kube.yml.
The reference to kube-master.yml in README.md is obsolete, so just drop it.
