          Considering the above two conditions, we need to check before sending customized RemoteInvocation:
          1. if the provider version is v2.7.0 or higher, send 'org.apache.dubbo.rpc.protocol.rmi.RmiRemoteInvocation'.
          2. if the provider version is v2.6.3 or higher, send 'com.alibaba.dubbo.rpc.protocol.rmi.RmiRemoteInvocation'.
          3. if the provider version is lower than v2.6.3, does not use customized RemoteInvocation.
