Description Joel Speed 2021-08-02 10:45:50 UTC

Description of problem:

When external cloud providers are enabled, the ExternalCloudProvider feature gate is included in the KCM feature gate list. As this is an openshift specific feature gate, the KCM does not recognise the value and logs an error that this is an unknown feature gate

Version-Release number of selected component (if applicable):


How reproducible:

100%


Steps to Reproduce:
1. Create a FeatureGate with `ExternalCloudProvider` as a custom feature gate
2. Observe KCM startup logs

Actual results:

Error is logged that the feature gate is unrecognised

Expected results:

No errors are logged
