### Why are the changes needed?
The metrics `kyuubi_operation_state_LaunchEngine_*` cannot reflect the state of Semaphore after configuring the maximum engine startup limit through `kyuubi.server.limit.engine.startup`, add some metrics to show the relevant permit state.

### Why are the changes needed?
The original dashboard dashboard template does not work for my use case:
In this PR:
1. I add the `baseFilter` variable, default value is `job=~"kyuubi"`.
2. apply the `baseFilter` for all expressions
3. add `baseLegend` for the legendFormat
4. Fix hardcode typos
5. remove the `sum` from the expressions for JVM
