[User-Story] - Add another (open workload) Load Generator

[franksn90]

Story

As a Dqualizer User (Domain Expert) who wants to run Resilience Tests, I want to have a load generator that can run open workloads to get accurate results. Closed workloads, as used by k6, are likely to deliver inaccurate results in resilience scenarios.

Acceptance Criteria

• Load testing can be executed using other load testing tool than k6.

Dependencies

Candidates to investigate

Joakim's HTTP Load Generator (deprecated) as "emergency solution"

Consider involving @EddeCCC in this task since he would be interested.

I think this would also be a good starting point for looking into implementing a plugin-system for dqexec's executors.

Wir haben uns für Gatling als nächstes Lasttest-Tool entschieden.
