Aside from removing the +nullable marker, the API changes looks good to me

Based on the CI failure, this looks like an invalid test case

CI failures are actually talking about ControllerConfig which is different, something has broken them though, @sandhya PTAL

+nullable marker has been removed. Infra CR is embedded within ControllerConfig. I'll take a look at the latest CI failures as soon as they become available.

Why does this one need the *Install suffix but the other platform gates did not?

https://github.com/openshift/api/blob/master/tools/codegen/cmd/featuregate-test-analyzer.go#L566 requires names of Installer feature gates to contain "Install".
#2423 is starting the work of renaming existing featuregates.

everettraven

Besides a small question on the naming of the gate compared to previous ones, this LGTM.

@JoelSpeed feel free to take a look
