[DMAAP] Introduce drprov-client

Introduce the drprov-client (replaces dbc-client) and use
it to provision data router feeds and subscriptions for
DCAE datafile collector and pm-mapper.
- Update the common dmaap provisioning template to use
  drprov-client instead of dbc-client.
- Add drprov-client image to the repository generator.
- Update the dcaegen2-services-common configMap template
  to generate JSON files suitable for provisioning data
  router directly.
- Update the dcaegen2-services-common deployment template
  to use drprov-client as an init container instead of
  dbc-client.
- Update dcae-datafile-collector and pm-mapper values.yaml
  to format feed and subscription data properly for
  drprov-client.
- Update versions for datarouter-node and datarouter-prov
- Update dependencies for DCAE datafile-collector and
  pm-mapper, which no longer depend on DMAAP bus
  controller.
