Initial Scenario testing and provisioning prototype

[dominikschubert]

Changes

• Introduced new InfraProvisioner to our testing library which can be used for more complex test setups such as CDK-based infrastructure definitions.
  • Set up tests directly via CDK (currently limited to single stacks, so you'll need to make sure the CDK app doesn't need any assets)
  • Manual setup and teardown can be registered if required
  • By default any S3 buckets created by CDK are cleaned before tearing down the stack again
  • Teardown can be skipped, to re-use the provisioned infrastructure between test runs. This is especially handy while writing test assertions and iterating over them. If you had to create/remove the stacks all the time, certain resources would make this impractical (e.g. clusters)
• Added initial scenario tests (most of them are still a kind of playground right now)

Looking forward to our new scenario tests in practise 😄
