Feature Overview (aka. Goal Summary)  

Provide support for cert-manager running on MicroShift 

Goals (aka. expected user outcomes)

MicroShift customer can use cert-manager on MicroShift to create certificates used by their components. 

Requirements (aka. Acceptance Criteria):

1. cert-manager can be installed using OLM on MicroShift. 
2. Optional: cert-manager can be installed using an rpm package (microshift-cert-manager)
3. The core cert-manager functionality must be available
   1. Support for integrating with external certificate authorities (incl. same list of issuer types)
   2. Tools to manage certificates (incl. dynamic creation)
   3. Automatic certificate renewal
4. MicroShift supports only the core k8s API. That means that all dependencies in cert-manager on OpenShift specific APIs need to be turned into weak references. This means to probe for the API to exist and gracefully handle if not present. The functionality associated with those APIs is not available on MicroShift. APIs known to be used by cert-manager and not available on MicroShift:
   1. *.config.openshift.io
   2. gateway.networking.k8s.io 

Questions to Answer (Optional):

Include a list of refinement / architectural questions that may need to be answered before coding can begin.  Initial completion during Refinement status.
