[User-Story] - Use Generic RQA Format

[franksn90]

Story

As a dqualizer user who specifies RQAs, I want to create composed RQA definitions using (multiple) monitoring requests, chaos experiments, load tests so I can examine my system for complex scenarios.

Acceptance Criteria

• I can create an RQA with a combination of load + resilience
• I can create an RQA with multiple load tests
• The RQAs can be persisted

--> specifying is enough for dqanalyzer

Dependencies

Additional context

Currently, you can only perform a (single) load test with the dqualizer. Later it should be possible to create an RQA definition, which includes monitoring requests, chaos experiments, load tests, and more. The new format should be a more understandable, generic RQA Format.
