While other jobs already have SYS_PTRACE capabilities, others don't. This PR adds these capabilities to jobs that can potentially generate dumps. The .NET createdump utility requires the ptrace() system call to attach to crashing processes and collect crash dumps. Docker containers don't have this capability by default for security reasons but in CI environments, it's ok.

Comparison explanation

Execution-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:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

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).

Nice, thanks! We should probably add the capability to the docker-compose.serverless.yml file too? 🙂

Nice, thanks! We should probably add the capability to the docker-compose.serverless.yml file too? 🙂

Good catch! I was checking and, for serverless, it will require more changes: env vars, volumes, the init flag... I have added the changes.
