Remove code to generate mapping id when creating a new mapping

[ymaheshwari1]

Current behavior

Currently, when creating a new mapping we are generating a random id for passing the same in the request, as the in parameter in the service is required.
But in current scenario as well, we are using the id returned from the api (which is an auto generated id) and we are using the same to identify the mappings.

Expected behavior

Need to remove the code for generating the id, once the id param will become optional
