chore(tracing): added tracing to messaging server

[michaelmass]

This adds an Opentelemetry tracing library to the messaging server. It can be configured by using the standard environment variables.

The trace initialization MUST be done before importing any other package since it instruments known libraries like express, knex, pg. This also requires the trace initialization to be synced.

The important environment variables for configuring tracing are:

• TRACING_ENABLED bool Enables the tracer
• TRACING_DEBUG bool Adds debug information about the tracing configuration
• OTEL_SERVICE_NAME string Sets the service name given to a trace
• OTEL_EXPORTER_JAEGER_ENDPOINT url Sets the Jaeger collector endpoint

This is an example of what the tracing library allows:
