Instead of maintaining the config schema as a yaml file, we
maintain it as a set of constants in a class. From the information in
these constants, we can generate a JSON schema (yaml) file, and an
php file containing optimized arrays for fast loading.
Advantages:
- PHP doc available to IDEs. The generated markdown file is no longer
needed.
- Can use PHP constants when defining default values.
NOTE: needs backport to 1.38
