Update Examples and IntegrationTest to use idiomatic naming (#706)

### Motivation

Since idiomatic naming is our new recommended setting, use it in
Examples and IntegrationTest.

### Modifications

Added idiomatic naming to all examples and made any necessary changes.
Plus a few modernizations, like moving to Hummingbird 2.0 and to
Prometheus 2.0.

### Result

More up-to-date examples, easier to copy out by adopters, they now get
our recommended starting settings.

### Test Plan

Ran and tested locally.
