Open batch un-enrollment design

Overview:

   Sunbird un-enroll service is built to facilitate user to un-enroll from an active open batch.

Problem Statement:

   How to empower user to un-enroll from an active open batch by their own.

Proposed Solution 1:

     We need to construct a new API for the same. This API needs the user to provide valid userid, batchid and courseid to un-enroll them. For this, there is a need to add a new column namely 'isunenrollmentallowed' (boolean) in the table 

Unenroll Service API:

    URI : "/v1/user/course/batch/unenroll"

          Request : 
                   {
                     "params": { },
                     "request":{
					“userid” : “adjad-asndk-djs73ne-dsmn”,
					“batchid” : “adhjka-djkah-dfhj-dmnsbd”,
					“courseid”:”djaskfsk-djashfkja-fsjdfjks-sfdnjskdh”
                              }
                        }
