fix(mojaloop/#3096): unable to upgrade knex dependency on centralLedger - mojaloop/project#3096

• added UV_THREADPOOL_SIZE config to CI command for running integration tests
• upgraded knex to latest version

The following issue mojaloop/project#3112 was created to investigate as to why the Integration Tests are so unstable when then Event Handlers are executing in-line. For the time being the above PR clearly separates the process which resolves the stability issue for the time being.

The following changes were made as a work-around:

• Integration Tests will no longer start the Event Handlers in-line. You will need to start the Central-Ledger Service as a seperate process (see updated documentation for more information)
• Documentation for Integration Tests updated to reflect the above requirement
• CI Job updated to start the Central-Ledger Service as a seperate Process prior to running Integration Tests
• Added comments to where the commented out code for the initialization of the in-line Event Handlers referencing the above story.
• Also made some changes to the Handler tests to handle failures instead of stalling the Integration Tests

chore: maintenance updates

• fixed audit issues
• added missing kafka topics from docker-compose init kafka container to ensure the CL Service startup is clean
