Implement GET /bulkTransfers

[elnyry-sam-k]

Goal:

As a Switch
I want to handle incoming requests on GET /bulkTransfers as per the ML FSPIOP spec
so that FSPs can use it to query the status of a given bulk Transfer

Tasks:

• Ensure designs are in place (Either create or validate existing ones)
• Implementation to provide functionality (may contain sub items) [@oderayi]
  • Bulk API Adapter implementation
  • Central Ledger implementation
• Unit tests [@oderayi]
• Tests in postman --> can be a separate story [@oderayi]

Acceptance Criteria:

• Designs are up-to date
• Unit Tests pass
• Integration Tests pass
• Code Style & Coverage meets standards
• Changes made to config (default.json) are broadcast to team and follow-up tasks added to update helm charts and other deployment config.
• Switch can handle incoming GET requests on /bulkTransfers as per the ML FSPIOP spec v1.0 / v1.1
