Related to: #193

PR #193 contains all of the YAMLs for high, medium, and low severity compliance remediations in to one PR. I'm breaking it down by severity level to make it easier for review.

The compliance operator finds the following failures that are designated as high:

$ oc get compliancecheckresult -A | grep high | grep FAIL
openshift-compliance   ocp4-cis-configure-network-policies-namespaces                    FAIL     high
openshift-compliance   rhcos4-e8-master-configure-crypto-policy                          FAIL     high
openshift-compliance   rhcos4-e8-master-no-empty-passwords                               FAIL     high
openshift-compliance   rhcos4-e8-master-sshd-disable-empty-passwords                     FAIL     high
openshift-compliance   rhcos4-e8-worker-configure-crypto-policy                          FAIL     high
openshift-compliance   rhcos4-e8-worker-no-empty-passwords                               FAIL     high
openshift-compliance   rhcos4-e8-worker-sshd-disable-empty-passwords                     FAIL     high

There is nothing here that is Telco specific. If this is required it needs to go into the product not something that has to be maintained by Telco.
