Add SDK Outbound Event Handler events for Discovery

[PaulGregoryBaker]

Goal:

As a DFSP connected to Mojaloop
I would like to use the bulk transfers use case
So that I can integrate bulk load disbursement calls with my core banking system

Notes:
This story is to add the events in the SDK Outbound Event Handler to complete the Discovery part of the transfer.
This story will only have unit tests to confirm completion.

Limitations
This story covers flows steps in 6 - 27 in the sequence diagram; these are the bulk discovery calls.
I.e. from the first Post to SDK SCheme Adapter, to the first returned bulkPartyAccept results through the PUT Callback when:
AutoAcceptParty is false and
synchronous is false.

Acceptance Criteria:

• Verify that the following events have been added
  • SDKOutboundBulkRequestReceived
  • SDKOutboundBulkPartyInfoRequested
  • PartyInfoCallbackReceived
  • PartyInfoCallbackProcessed
• Verify the unit tests are in place
