## What changes were proposed in this pull request? * Fix snapshot multiple-chunk bug. Currently, when leader install a snapshot(multiple chunks) to a newly joined follower, leader will send multiple InstallSnapshot RPCs. However, each RPC will create a tmp dir with Random UUID, place the chunk in this tmp dir, and only renames the last tmp dir to sm-dir. In this PR, I propose to create tmp dir using request.uuid(), which remains unchanged among multiple RPCs. * Fix Grpc Stream errors. Currently In grpc.proto, InstallSnapshot is declaimed as client-end streaming rpc, but it is actual bi-directional streaming rpc. In this PR, I addded stream to InstallSnapshot proto so that it becomes bi-directional. * Support snapshot file hierarchy. Currently all files of a snapshot will be placed in statemachine dir and file hierarchy is flattened. In this PR, I name each file using its original filename (which contains hierarchy information). ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/RATIS-1587 ## How was this patch tested? * Unit Tests. It passed all unit tests in my machine (MacOS 12.13) * Manual Test. I packaged this version of ratis and tested its snapshot functionality in our project Apache IoTDB, and everything is working as expected -- This is an automated message from the Apache Git Service.
