[OOM] Fix Feed Provisioning for DFC

   Cmd :"grep -o '"logURL":"[^"]*' "$file" | cut -d '"' -f4"
   filters more then one logURL like below from feedConfig response log,
   If both subs/pubs are present, which corrupts application config.

   https://dmaap-dr-prov/feedlog/1
   https://dmaap-dr-prov/sublog/1

   Requirement is to filter only feedlog URL, with changes script
   should correctly filter URL: https://dmaap-dr-prov/feedlog/1.
