Need to update task parameters for multiple pipelines dynamically using excel file

The SnapLogic Metadata snappack can be used to build a pipeline to perform such updates. The flow would be:

1. Read the Excel file using File Reader and Excel Parser snaps
2. For each Task referenced in the file, use the Metadata Read snap to read the task information
3. Use a Mapper snap to update the Task information with the required parameter/snaplex changes
4. Use the Metadata Update snap to update the Task with new metadata
