Batch Implementation - Improper error callbacks generated by switch

[vijayg10]

Summary:
The error callbacks generated by the switch are erroneous. Observed following issues

• The error callback is sent as POST /transfers instead of PUT /transfers/{ID}
• There is no transferID in the body for error callback and causing the validation error in FSP simulators {"missingProperty":"transferId"},"message":"must have required property 'transferId'"}
• The source header should be set as switch

Accptance Criteria

• Verify that the header code is compared to the non-batching handlers. There are other missing information that should be added.
• Add unit test to validate the published kafka notification messages.

Severity:
(Low, Medium, High)

Priority:
Critical

Specifications

• Component (if known): central position handler with batch processing
• Version: feature branch for batch
• Bug found/raised by: @vijayg10

PRs:

• feat(mojaloop/#3636): batching implementation for position prepare messages central-ledger#968
