What does this PR do?

  • Add DD_APM_TRACING_ENABLED and apmTracingEnabled to disable APM Tracing
  • Add tracesource span tag _dd.p.ts tag
  • Add standalone products: APM, ASM, DSM, etc
  • if apm tracing is disabled:
    • Set TraceSourcePrioritySampler which drops all the traces without _dd.p.ts tag as tracer priority sampler
    • Disable stats computation and include 'Datadog-Client-Computed-Stats' header
    • Add _dd.apm.enabled: 0 tag on onSpanStart
    • Drop certain headers on onSpanInject
    • Check sampling priority received from upstream on onSpanExtract
    • Set a 1req/min ratelimiter when ASM is enabled
