Look in all source folders for .yml and .md files

[r-hempenstall]

Describe the bug

When running dbt, it looks inside the models folder for .yml and .md files but does not look inside the snapshots folder. This is a bit ugly when trying to specify the sources for snapshots as the queries and the snapshots and their documentation end up in different sections of the project.

Steps To Reproduce

Create a .yml file specifying a source for a snapshot in the snapshots folder. It won't be picked up by dbt and instead you'll get an error about not being able to find the source.

Expected behavior

When I run the snapshot function I would expect the steps described above to compile and create my snapshot using the correct source.
