Schedule Client not correctly encoding the URL resulting in pre-upgrade job failure

Reproduction Steps:

• Create a schedule with name No.10 - 0014002 AND No.16 0015006 in 6.9.x instance

• Start the schedule

• Trigger instance upgrade

• Observe failure in pre-upgrade job pod when CDAP is running on k8s.
  
  

Simple fix could be to first encode the URL and then resolve it here:
URLEncoder.encode(url, "UTF-8");
