Mark Adams 6eb01409da Fix validate_reload by returning the validated value (#1378)
* Fix validate_reload by returning the validated value

When '--reload=RELOADER_TYPE' was implemented, `validate_reload()` was
added but in one of the last refactorings, it lost the return statement
at the end of the function. As a result, the '--reload' config value was
totally broken.

This resolves the issue by adding the missing return.

* Fix tests by changing --reload to always require an argument

- '--reload' always requires an argument now
- Added 'auto' as the default value for '--reload'
