Exception in operator from operatorsdk

[kornys]

I don't know if it is an issue but I see sometimes this issue when I executing tests in parallel in operator

it happens when first test removed managedkafka resource in some namespace A and second test tried to recreate different managedkafka in namespace B

I added checker for operator log in this PR https://github.com/bf2fc6cc711aee1a0c2a/kas-fleetshard/pull/92

@ppatierno do you think it is an issue? I think it does not affect test because test without checking logs pass and managed kafka is recreated.

Issue is not related to our operator but to opertatorsdk, closing
