apache#7577. We don't use the latest version of junit, so I have changed the unit tests to use the older version. That should be the only difference from the branch-2.6 change upstream. Upstream PR description below:
Currently, sleepForRetries (the sleep time between retry attempts during replication) is only configurable globally via the replication.source.sleepforretries configuration property. This makes it impossible to tune behavior for individual replication peers that may have different requirements.
This change would add support for overriding replication source config values on a per-peer basis, with fallback to the global configuration when not set.
