[KYUUBI #1513] Added support liveness and readiness for kyuubi pod

### _Why are the changes needed?_
It is better to support `livenessProbe` and `readinessProbe` for indicating whether the container is running.

### _How was this patch tested?_
- [ ] 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.readthedocs.io/en/latest/develop_tools/testing.html#running-tests) locally before make a pull request

Closes #1513 from murong00/branch-1513.
