Added Security, Policy, Observability & Plugin Checks

Security Checks:
Checking for security config on the cluster, consisting of capability, privilege, host network, host path and
connectivity checks

Policy Checks:
Validating CPU Manager and Topology Manager policies against the settings from PDF

Observability Checks
Checking existence and health of prometheus, node-exporter and collectd pods

Plugin checks
Checking for the existence of multi-interface pod (multus) and validating the list of CNI against the PDF

Also added usage information and pdf field information to userguide.rst file in the docs section. For reference, I have added a PDF.json in sdv/docker/sdvstate/settings section file to look at necessary configuration required for the kuberef validation.
