message: build: enable verbose_failures for CI
  When a tests fails in CI it will be useful that failures are disabled in CI as not all users have SSH access.
  Also this adds `flaky_test_attempts` to 2 as this morning I noticed a flake on a tests which failed but passed when force pushing
diff: # Save downloaded repositories in a location that can be cached by CircleCI. This helps us
  # speeding up the analysis time significantly with Bazel managed node dependencies on the CI.
  build --experimental_repository_cache=/home/circleci/bazel_repository_cache
  +
  +# Retry in the event of flakes, eg. https://circleci.com/gh/angular/universal/1768
  +test --flaky_test_attempts=2
  +
  +# More details on failures
  +build --verbose_failures=true
