[CWS] Allow specifying cgroup managers for dumps generation

[lebauce]

What does this PR do?

Allow automatically generating activity dumps for systemd services.

Motivation

Currently, generating activity dumps for systemd services is supported but it's a manual step.
This PR allows to:

• Automatically generate dumps for systemd services
• Specify the cgroups for which we automatically generate the dumps.

Describe how you validated your changes

Set runtime_security_config.activity_dump.cgroup_managers to systemd and check that
activity dumps are only generated for systemd cgroups.

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

• ✅ = significantly better comparison variant performance
• ❌ = significantly worse comparison variant performance
• ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

3. Its configuration does not mark it "erratic".

Do we really need that ? I think there is a replace anyway
