[jira] [Created] (APEXCORE-497) Create a DelayNode for DelayOperator

Sandesh created APEXCORE-497:
--------------------------------

             Summary: Create a DelayNode for DelayOperator
                 Key: APEXCORE-497
                 URL: https://issues.apache.org/jira/browse/APEXCORE-497
             Project: Apache Apex Core
          Issue Type: Improvement
            Reporter: Sandesh


One of the design elements I have seen in Apex is, while deploying only required objects are deployed. For example Stream persistence reservoir was created only when it is required. So in the same spirit, we can have the DelayNode for Delay Operators.

Delay Operator related changes happen for the control tuples in GenericNode.

Implementation Idea: 
1. Create functions for handling each control tuples in Generic Node
2. DelayNode extends GenericNode
3. Overrides the required functions created in step 1.
4. During deployment based on the operator type, create the required Node.
