set local fallback and correct domain

[BenTheElder]

• jobs run in test-pods but the bazel cache is in default, correct the cache URL
• also set local fallback so if the cache is unavailable the job doesn't fail..

is default referring to the namespace? if so, why don't we put the bazel cache in its own namespace?

It is, and uh, it seemed un-necessary? everything else running in the build cluster is either kube-system or test-pods. We could move it to a namespace but I'm not sure what we gain from that really. It just makes your kubectl calls longer if you aren't using RBAC :+)

FWIW the Prow services cluster uses all default namespace with URLS like http://tide/

@BenTheElder: How many optometrists does it take to change a light bulb? 1 or 2? 1... or 2?
