[FA] Always instrument methods

[coignetp]

What does this PR do?

This PR update the instrumentation logic of all the check methods.
Here are the following changes:

• All methods of AGENT_CHECK_DEFAULT_TRACED_METHODS are always instrumented (meaning wrapped with a tracer.trace)
• If the method is an entry-level method (meaning that it's called by the agent directly, and not one of the internal methods), it calls the configure_tracer method before running the method.
• configure_tracer samples all traces if integration_tracing or integration_tracing_exhaustive is true
• Attach to dd_trace_id and dd_parent_span_id if they exist in the instance.

Next step is to read the sampling from the agent config, and let the agent pass the trade ID and the parent ID through the instance

Motivation

The goal is to be able to enable or disable tracing at runtime. (PR in progress)

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
