fix(mojaloop/#2734): failures in daily cron job running gp tests (#146)

fix(mojaloop/#2734): failures in daily cron job running GP tests - mojaloop/project#2734
- fixed logging to correctly display request logs. this is needed to help debug issues
- re-factored config-loading as this was badly being being handled, which impacted unit/integration tests etc.
- added unit tests for config-loading
- added support for `CONFIG_OVERRIDE` env var to support using example.env for unit/integration tests, with default being `.env` when running `npm start`.

chore: maintenance
- updated dependencies
- updated husky to the latest version, and moved config from package.json to .husky folder
- replaced module-alias with native import alias's
