allow passing arbitrary config options to kube daemons

[Ricardo Rocha]

In some deployments different kube daemons need special configurations, example for kubelet:
--event-qps int32 If > 0, limit event creations per second to this value. If 0, unlimited. (default 5)

Similar qps params exist for other daemons, and other params also need to be tuned in some deployments for speed improvements.

The simplest way to allow this is to add a new label per daemon to define extra configs, to be done via the cluster template or directly on cluster creation.

    k8s: allow passing extra options to kube daemons

    Define a set of new labels to pass additional options to the kubernetes
    daemons - kubelet_options, kubeapi_options, kubescheduler_options,
    kubecontroller_options, kubeproxy_options.

    In all cases the default value is "", meaning no extra options are
    passed to the daemons.
