Encoding the special characters in the resource identifier

Encoding the special characters in the resource identifier

- during passthrough requests, if the resource identifier had special
  characters then the resource was not returned by the sdnc
- fix is to do proper encoding when the passthrough read operation is
  made
- Introduced a utility to convert the resource-id to encoded resource id
  and then make the same request using resttemplate
- Added testware for the same
- Inspected code for the changed files and fixed the issues
