Option to retry failed dependency fetches?

[richardstephens]

Some of the packages we push to our private github packages repo do not have source jars associated with them. We've noticed that builds that depend on these will sometimes fail intermittently.

It looks like what's happening is that github packages will intermittently return a 400 Bad request instead of a 404 for the non-existant source jar. We've filed a ticket with github support but it would be nice if we could have bazel retry the failed request.
