Position event partitioning strategy enhancement to use AccountId

[PaulGregoryBaker]

Goal:

As a <stakeholder|persona>

I want to

so that

Note
During the transfer characterisation performance workstream, it was noted that the kafka key's for position updates were not correctly aligning to the accounts that were being updated. This story is to rectify that, so that congestion in the position handler is removed.

(This code (Kafka.proceed) is stilling in central services shared. This should be removed and added to the central services.)

Acceptance Criteria:

• Verify that position events are keyed based on the database position account Id and base on the use case
  • prepare will be the Payer DFSP position account Id
  • fulfil will be the Payee DFSP position account Id
  • Abort will be the Payer DFSP position account id
• The following components will need to be updated
  • Position handler
  • Fulfil handler
  • Timeout handler
• Integration tests should be added to validate the partitioning strategy. (i.e verify message keys are the account id for the appropriate use case)
• Verify that any new queries that are added (e.g. timeout handler to get position account id's) should be cached.
