Adam Cozzette 802e1b99b2 Attempt to mitigate "docker pull" failures
Lots of CI tests have been failing recently with error messages like
this from "docker pull":

  Error response from daemon: unexpected EOF

This seems to be an issue affecting other projects as well:
https://forums.docker.com/t/docker-pull-causes-error-response-from-daemon-unexpected-eof/88608

This commit tries to mitigate the problem by periodically retrying
failed Docker pulls.
