Add cmk addon helm chart

Add cmk addon helm chart

The chart follows the instructions laid out in the CMK operator
manual, with the following notes:
- The nodes are prepared by running each CMK subcommand as a Pod
  instead of running cmk cluster-init.  The first reason for this is
  that the existing addon only deploys CMK to the worker nodes in the
  cluster.  This is not possible using cluster-init without explicitly
  providing the list of worker nodes to cluster-init, and this list is
  unknown by helm.  Instead it is sufficient to rely on the
  node-role.kubernetes.io/master:NoSchedule taint.  The second reason
  is that cluster-init creates resources which are unknown to helm,
  thus uninstall does not behave as expected.
- The v1.4.1 version of CMK is chosen.  In v1.5.2, the description key
  of the cmk-nodereport resource is not correct.
- All values listed as possibly requiring modification are exposed in
  values.yaml
