Include cause for retries into retry metrics

Browse Source 
By looking at the metrics we want to know how often a certain error
causes requests to be retried. E.g. it's good that we retry requests on
LOCK_FAILURE, but if LOCK_FAILURES cause too many retries we want to
investigate why they are occurring that often. At the moment the retry
metrics only tell us how often requests were retried but not why.
