The Insights operator appears to be emitting events repeatedly, only on techpreview clusters in CI. The problem surfaces as a test failure:

[sig-arch] events should not repeat pathologically expand_less 	0s
{  1 events happened too frequently

event happened 133 times, something is wrong: ns/default namespace/default - reason/Unable to find REST mapping for %s/%s: %w InsightsDataGather.config.openshift.io%!(EXTRA string=v1, *meta.NoKindMatchError=no matches for kind "InsightsDataGather" in version "config.openshift.io/v1")}

Problem appears to be only surfacing on techpreview clusters, but it spans many providers:

We've identified 138 occurrences in the last two weeks on 4.13, but most likely it's affecting every single job run, and subsequently failing the job run. It looks like virtually all techpreview jobs are at 0% pass rate and this is likely involved.

I believe the problem is impacting 4.12 as well and thus likely needs a backport.

On the surface it looks like two problems here:

1. the fact the event emits repeatedly (every reconcile loop perhaps?)
2. a bad format string

Given this appears to be 100% failing all runs for most techpreview jobs, rating Sev=Important. (Repeated events can be a strain on etcd)
