testsys-launcher: Apply brupop/cert manager manifests

[jpmcb]

Issue number:

N/a

Description of changes:

This patch enhances the testsys-launcher CDK by applying the cert-manager and brupop manifests.

However, the CDK breaks on very large manifests (like with many CRD versions) or with many components: https://github.com/aws/aws-cdk/issues/19165 so this should stay in draft until that can be handled better.

Testing done:
