[EPIC] Improve traceability in the API

[Tansito]

What is the expected enhancement?

When we have an error or we want to analyze a succession of events we don't have enough information from traces or the traces that we have are not the best ones. My proposal is to add traces in:

• Views: for requests and responses with not sensitive information like id of a Job or a Program
• Serializers: add traces with interesting information in the different overrided methods
• Scheduler / Ray: review traces that we have here
