We set index_upload_policy to Always and index_upload_gcs to False, because this way Bazel CI ignores build failures and doesn't push the final artifacts to Kythe.

Setting index_upload_policy to Never would be even better, however this only works if Bazel can successfully build all the targets returned by the query, which is currently not the case and would need further cleanups.
