PoC disable tracing via remote-config

[ygree]

What Does This Do

This PR implements tracing disabling by stopping trace publishing but keeping span creation.

This change satisfies one of the `TestDynamicConfigTracingEnabled' system test scenarios where tracing is initially enabled and then disabled via remote config.

Motivation

In-app APM Service Disablement RFC
