Remove enableTracing

[HazAT]

Currently, we offer multiple options to configure sampling for tracing:

• tracesSampleRate
• tracesSampler
• enableTracing

But when to use which, is sometimes not obvious to our users. What makes this worse is that implications of some of them differ across SDKs, for example when it comes to Trace Propagation. In Python for example, propagation of trace headers works without any tracing config options in place being set. In Go, you need to at least set enableTracing to true in order to achieve the same result.

Goal is:

• remove enableTracing in all SDKs
• make tracesSampleRate the default, also in config snippets
• explain how to get more out of sampling by using the tracesSampler function
• mark enableTracing in all SDK docs as deprecated (config option page)
