### Description of PR
In current ObserverReadProxyProvider implementation, we use the following code to invoke msync RPC.
```java
getProxyAsClientProtocol(failoverProxy.getProxy().proxy).msync();
```
But msync RPC maybe send to Observer NameNode in this way, and then failover to Active NameNode. This can be avoid by applying this patch.
