### _Why are the changes needed?_ close #3150 Expose the metadata store requests metrics: ``` kyuubi.metadata_request.total kyuubi.metadata_request.failed kyuubi.metadata_request.retrying ``` `total` and `failed` are cumulative, `retrying` is not. If there are still some retrying metadata requests, we shall not restart the kyuubi server, otherwise, some metadata requests will lose. ### _How was this patch tested?_ - [x] Add some test cases that check the changes thoroughly including negative and positive cases if possible - [ ] Add screenshots for manual tests if appropriate - [x] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request Closes #3149 from turboFei/metadata_store_metrics.
