Harden the Mojaloop Connector to support FX flows as an FXP, Payer DFSP, Payee DFSP

[PaulGregoryBaker]

Goal:

As a DFSP wanting to make and receive FX payment in mojaloop I want to ensure that the FX implementation POC is matured so that I can make use of the Mojaloop connector to build my integration for the FX use case to my backend system.

As a directly connected Foreign Exchange Provider participating in a mojaloop I want to ensure that the FX implementation POC is matured so that I can make use of the Mojaloop connector to build my integration for the FX use case to my backend system.

Note: FXPID are obtained through configuration in Payer DFSP

Acceptance Criteria:

• [x] Verify that error cases are mapped and documented.
  • [x] Payer DFSP
    • [x] Check if FX is required
    • [x] Obtain FX quote
    • [x] Check conversion acceptance with Core connector
    • [x] Initiate FX Transfer
  • [x] Payee DFSP
    • [x] Get Parties add supported Currencies (Config)
  • [x] FXP
    • [x] POST / PUT fx Quotes
    • [x] POST / PUT fx Transfers
• [x] Verify that the functional test are added to test the error cases.
• [x] Verify that unit test are added
• [x] Verify that all mojaloop core standards are met

Note: because API is being use this may need to be functional TTK test and not integration tests.
