Add yaml load and key delete to consul-loader-container

Enhance Consul loader to:
   -- Convert YAML configuration files to JSON before storing the configuration into Consul
   -- Provide an option to delete a Consul key so that a component's configuration can be
      removed from Consul when the component is undeployed.
Use the ONAP integration team's Python image (integration-python:8.0.0) as base image.
