Description of problem:

When updating our operator it sometimes get stuck with a conflict error:


 message: 'error updating CRD: toolchainconfigs.toolchain.dev.openshift.com: Operation
      cannot be fulfilled on customresourcedefinitions.apiextensions.k8s.io "toolchainconfigs.toolchain.dev.openshift.com":
      the object has been modified; please apply your changes to the latest version
      and try again'


The failed InstallPlan: https://gist.github.com/MatousJobanek/ea9fe074f8e54f56aa07cdcbdfb4e1b0


How reproducible:

It happened in our OSD cluster after creating these resources:

After a few of updates, we hit the error.

The operator update get stuck

Expected results:

The OLM should retry and continue with updating the operator
