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 incorrectly being handled all-over the place, 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
