Yanqin Jin da4aa59b4c Add read retry support to log reader (#4394)
Summary:
Current `log::Reader` does not perform retry after encountering `EOF`. In the future, we need the log reader to be able to retry tailing the log even after `EOF`.

Current implementation is simple. It does not provide more advanced retry policies. Will address this in the future.
