Draft: lib: logger implementation for alerts and traces

To give more observability and escalate runtime problems to be followed up, this MR creates a "logger" library. Currently, the idea is to connect with GitLab Alerts #23, and AWS CloudWatch logs for the traces.

Still in progress, I want to make sure the library follows good NestJS patterns and is well integrated.
