Do you need continue-on-error: true here?

[tmshort]

Do we need to add this one to operator-controller?

[rashmigottipati]

Looks like continue-on-error: true is needed here so the override step can run even if the test fails.

[grokspawn]

Argh. I threw this one in this morning, realizing that one of my later PRs was going to need to be able to override go-apidiff. And missed the continue-on-error.
Yes, I think we should also have this in op-con.
Updated.
