Description of problem:
The display logic was updated in https://github.com/openshift/console/pull/5082 to hide the "install" button when an annotation was set. It will not be possible for Marketplace Operator to set these annotations in the 4.5 timeframe.
In 4.5, browsing a Marketplace offering in OperatorHub does not have a button linking to the Marketplace.
"Purchase" button appears linking to the Marketplace. A secondary install button is also present next to it.
Have a PR up for this; waiting for review/merge: https://github.com/openshift/console/pull/5306
Checked on OCP 4.5 cluster with payload 4.5.0-0.nightly-2020-05-13-202437
Now the button text is rolled back to "Purchase" if marketplace.openshift.io/remote-workflow annotation is set and marketplace.openshift.io/action-text annotation is not set. And "Install" button will always show up no matter these annotations exist or not.
