  }

Output :

Process the request and save the request parameters to Experiment-Definition Cassandra Table with status "SUBMITTED"
Response : "Experiment Submitted Sucessfully "

Note :

All fields are mandatory
Same Experiment will not be allowed to submit again unless the status of the experiment is FAILED
If the experiment is submitted more than once , will send a response "Experiment already submitted"
