testing: Use GCR image to prevent Docker Hub rate limits

[spowelljr]

Some of our CI machines are running into rate limiting pulling images from Docker Hub. Change images to pull from GCR instead.

#3 ERROR: failed to copy: httpReadSeeker: failed open: unexpected status code https://registry-1.docker.io/v2/library/alpine/manifests/sha256:b5a5b7ce4eabc8414bf367761a28f4e8b16952ce5de537c15ed917b71b245f11: 429 Too Many Requests - Server message: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
