Comparison explanationExecution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard. Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Summary of changes
add a process tags field next to where the service name is added in the snapshot json.
dotnet version of DataDog/dd-trace-java#8779
Reason for change
AIDM-195
Implementation details
I wanted to inject the setting from
dd-trace-dotnet/tracer/src/Datadog.Trace/Debugger/DebuggerFactory.cs
Line 30 in 79b266b
Another option was to put it in the debugger settings, but it felt out of place as those settings are specific to the live debugger, not a repeat of global tracer settings.
In the end I decided to inject a little bit so that I could specify the value in tests.
Test coverage
just made sure the test that checks json correctness includes this
