Updated examples and integration test with the new servers syntax (#688)

### Motivation

A drive-by fixup, I noticed the warnings when running the integration
test locally.

### Modifications

Fixed up the examples and integrate test to use the new syntax. This
also meant regenerating the two examples that check in generated code,
which took in a few more changes since 1.0.

### Result

Syntax matches our current best practices.

### Test Plan

Looks good locally.
