Boilerplate update removing `operator-sdk generate`

[2uasimojo]

  • Ability to securely suppress boilerplate deltas in GitHub via .gitattributes. (Suppression is not included in this PR.)
  • The operator image is now built against golang 1.16 (was: 1.13).
  • The OLM catalog images are now built against registry 4.8.0 (was: 4.7.0). This upgrade includes some security fixes.
• Cleanup and code regeneration pursuant to the above.

This will now need to be reconciled with #580. I think we should just be able to revert the last four commits.

[dastergon]

@2uasimojo how can we proceed here?

[2uasimojo]

I'm working with @sam-nguyen7.

I've finished rebasing and cleaning up #589, which supersedes this, so we can close.
