Previously, custom snippet templates were loaded from
org/springframework/restdocs/templates and the default templates were
loaded from org/springframework/restdocs/templates/{$formatId}.
Without relying on the ordering of the classpath, this made it
impossible to provide a custom template for a specific format.
This commit updates the locations that are checked for snippet
templates. The following locations are now checked in order:
1. org/springframework/restdocs/templates/${formatId}/${name}.snippet
2. org/springframework/restdocs/templates/${name}.snippet
3. org/springframework/restdocs/templates/${formatId}/default-${name}.snippet
The second location is provided largely for backwards compatibility
with 1.0. Users are expected to use the first location to provide
any custom templates, with Spring REST Docs provided templates for
all of the built-in snippets in the third location.
