Holden Karau 90ac9f975b [SPARK-32004][ALL] Drop references to slave
### What changes were proposed in this pull request?

This change replaces the world slave with alternatives matching the context.

### Why are the changes needed?

There is no need to call things slave, we might as well use better clearer names.

### Does this PR introduce _any_ user-facing change?

Yes, the ouput JSON does change. To allow backwards compatibility this is an additive change.
The shell scripts for starting & stopping workers are renamed, and for backwards compatibility old scripts are added to call through to the new ones while printing a deprecation message to stderr.

### How was this patch tested?

Existing tests.

Closes #28864 from holdenk/SPARK-32004-drop-references-to-slave.
