[joelanford]

Fixes #378

@joelanford Would this also need to go into operator-sdk directly as well?

@acornett21 The code bases are similar, but I can't remember if we have the same updater and wait for deletion logic there.

@joelanford ahh okay, I assumed this issue was coming from an operator, but now I see that stackrox has a direct dependencies on this lib. Just wanted to make sure we cover the bases.

@joelanford note the unhappy linter...
