the "query url" part doesn't know about (storage) content types. and it
returns the file name, so we can't let it detect compression but throw
that part away, else we get the uncompressed filename instead of the
compressed one (exactly what happens with v7 now).

that's why we originally made the client/GUI make the choice:

iso download dialogue:
- query url with compression support
- allow overriding (de)compression
- pass (de)compression to download if set

other download dialogues (currently only templates):
- query url without compression support
- don't offer (de)compression choice
- (de)compression is never set, thus never passed to download

in addition, the download backend (which knows about content types) also
only allows decompression for isos (at least for the time being, if we
ever revisit and allow plain container template archives then all of
this is moot anyway ;))
