## What changes were proposed in this pull request? since we have [RATIS-1399](https://github.com/apache/ratis/pull/496), each `notify` of all the log senders will be executed in parallel ， default using ForkJoinPool ，which has a fixed num of threads in thread pool (default the same as the num of cpu core) in GrpcLogAppender.java, `synchronized` is used for two purposes: 1 protect `wait()` 2 protect variables like `pendingRequests`, `pending` , etc. this patch add a separate RWLock for the second case ， and keep `synchronized` only for wait and notify, thus any slow IO option will not block notify. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/RATIS-1400 ## How was this patch tested? unit test -- This is an automated message from the Apache Git Service.
