Each content type has a predefined location in a storage where they can be
found. iso and vztmpl files can now be found and and also uploaded in
subdirectories of those locations, too.
Add a parameter "recursive" (default off) to the API at
storage/{storage}/content, to perform this search.

Changes since RFC:
* Separate tests for existing and new stuff into 2 patches
* Die when .. appears in a path
* Make feature opt-in (relevant for symlinks)
