python: Expose virStorageListAllStoragePools to python binding

The implementation is done manually as the generator does not support
wrapping lists of C pointers into Python objects.

python/libvirt-override-api.xml: Document
python/libvirt-override-virConnect.py: Add listAllStoragePools
python/libvirt-override.c: Implementation for the wrapper.
