Upgrading from v1.3 to v1.4

Removal of the cert-manager operator package on Red Hat Marketplace

Since cert-manager v0.15 there has been a package for cert-manager on Red Hat Marketplace, but this has now been removed because it was not maintained and was found to be unreliable: #4055 #3732 #436

It is replaced by a new package which is generated via the Community Operators Repository, and which is therefore available on OperatorHub.io, OpenShift Container Platform and OKD.

Please uninstall the existing cert-manager package and re-install by following the OLM Installation Documentation.
