testing: Use low-reputation billing account

[grayside]

This change swaps out the "standard" billing account for a "low reputation" billing account. This is intended to see if our automated testing process can surface more accurate end-to-end error conditions faced by folks using this blueprint in a wider range of circumstances.

Considerations for merge include:

• Are the error messages sufficiently distinct from other errors we are likely to surface in testing that we can simply switch, rather than establish a "billing account matrix" and test both ways?

[grayside]

Lint error is because of temporary change to variable defaults.

[grayside]

I think we're good to make this change and observe for a while. I've now limited this to just the billing account and further change exploration will be separate.

@grayside did you want this one merged, and #79 closed unmerged?

[grayside]

Yes, this is one I want merged. #79 is for additional experimentation but I don't have a current next experiment so we can close.

Glad I merged this second in the queue. There's some interesting errors after merging #58

First error:

suffix-example-apply: Error: "404" is not less than or equal to "299"

DefineApply from tests runs during apply. This came up because the placeholder didn't successfully deploy. We may want to add placeholder job polling like we do on client deploy job polling.

On retry:

suffix-example-apply: Error: Error creating service account: googleapi: Error 429: A quota has been reached for project number NNN: Service accounts created per minute per project.

This is temporal?

Cause of build errors in #84

API issue looks temporal, not re-created.
