[cert-manager] Tooling for deployment and cross-configuration of cert-manager and external dependencies

[nate-double-u]

Create a means to easily install and configure various combinations of cert-manager, external dependencies (i.e ingress controllers) and cert-manager custom resources for local development and testing purposes.

cert-manager is a Kubernetes addon that helps with management and issuance of TLS certificates in a Kubernetes cluster. In practice, such a TLS setup can involve a deployment of cert-manager, cert-manager custom resources and some external tools, such as Vault or some ingress controller implementation and all of these tools also need to be configured to work together. As cert-manager developers working on new cert-manager integrations, trying to reproduce bugs etc, we often spend significant amount of time setting up and cross-configuring cert-manager and these external tools. It would be great if we had a way to easily deploy cert-manager, cert-manager resources and any required external tools, all configured to work for a particular TLS setup scenario.
