Enable sending traces to Tempo

[ausias-armesto]

The goal of this epic is to enable the phttp applications to send traces to a Trace collector like Tempo. This feature will allow to better identify bottlenecks in the execution of load tests.
The current issue is that we face when we execute load tests, is that we are not able to identify where is the time being spent. We should be able to see traces starting from the client side in this case the exit-app, availability-monitor and the discovery-platform.

The implementation should be compliant with:

• https://opentelemetry.io/
• https://opentelemetry.io/docs/languages/js/

Traces should be sent in OTLP protocol
The Traces collector is deployed in Kubernetes and its internal url is : http://tempo-distributor.monitoring.svc:4318
For debugging you can execute kubectl -n monitoring port-forward service/tempo-distributor 4318:distributor-otlp-http to open a tunnel to the collector, and then use the url: http://localhost:4318
