Release 2.5.1

Summary

From now on, Datadog Continuous Profiler is released within the MSI on Windows. It is deactivated by default. Set the environment variable DD_PROFILING_ENABLED=1 to enable it.
You can now instrument methods through configuration thanks to the DD_TRACE_METHODS variable. Public documentation change is in progress (Install 2.6.0 instead if you want to test this feature as we have fixed one issue when using different versions between Custom and Automatic instrumentation).
Finally, the release also brings support for B3 and W3C headers (#2536).

Changes

Runtime metrics are publicly available. They can be enabled by setting the DD_RUNTIME_METRICS_ENABLED environment variable to 1. For more information: https://docs.datadoghq.com/tracing/runtime_metrics/dotnet/
Changes in the trace buffering logic (#1151) :
- Traces are now serialized as soon as possible, instead of every second. This reduces the lifetime of Span objects, which in turn should decrease the number of gen 1/2 garbage collections
- Whenever adding a trace would cause the buffer to overflow, the contents are immediately flushed. This should reduce the number of dropped traces for customers with a very large amount of spans
