feat: improve open telemetry tracing instrumentation

[thepabloaguilar]

This PR introduces two new configuration options under tracing section:

• samplingRatio: Allow the users to define how much the sample they want to send to their collector, it's handy to let the user control the volume going out
• propagators: Allow the users to define one or more propagators, this is specially useful when dealing with propagator migrations or in the environment where each team can decide what to use

Both additions are non breaking change as I kept the default value the same!

More information in the tracer resource was added as well as new span attributes for evaluation methods!

Additionally I've changed the imports of go.opentelemetry.io/otel/semconv to use the latest version as every import were using a different and old version! This also shouldn't break anything

Closes #2978
