Fix inconsistent fields for resource settings on service for API docs

In API docs, `CPU` and `Memory` were used for resource settings on
services. The actual settings should be `NanoCPUs` and `MemoryBytes`.

This fix address the inconsistent fields between API docs and actual
settings.

This fix fixes #24058.
