fixes#284
We will create and write a log during submit a new session (like spark-submit) but we don't delete or overwrite it. This PR aims to add a time config to decide if we need to overwrite a session submit log.
The log path template is `KYUUBI_WORD_DIR/user/$engine-log.$index`. We will increase the `index` automatically if a user create some session concurrently.
After this PR. The log path template is `KYUUBI_WORD_DIR/user/$engine.log.$index`.
