Make reindex process less brittle

1.  Catch bulk index failures and retry them as single indexes.  This should
help with really really large pages.
2.  Catch failures in those single indexes and backoff for some time and
retry.
3.  Make the batch size and the number of errors to try to backoff from
configurable.
