### What would you like to be improved?

The following issue only achieves `FlinkSQLEngine` process, but users have no way to set `--jar` and `--library` options in Kyuubi. We should achieve this in `KyuubiServer` process too.

https://github.com/SteNicholas/incubator-kyuubi/commit/dd5a704342334feb24eae981d184943f618dd228

We can put `--jar` and `--library` options in `kyuuubi-default.conf`, and `KyuubiServer` process load these options.

### How should we improve?

`KyuubiServer` process loads the Flink `SQL Client startup options` in `kyuuubi-default.conf`. And then `KyuubiServer` transforms the options to standard Flink `SQL Client startup options` and passes them to `flink-sql-engine.sh` when the `flink-sql-engine.sh` process will be started.

The `kyuuubi-default.conf `options like the following.
```
flink.client.option.jar foo.jar
flink.client.option.library /foo/bar
```

Now `flink-sql-engine.sh` startup options are nothing, so users can't set any options.
