Skip testing most compression methods by default
The test suite is now reaching the C.I. timeout. In order to reduce the
overall runtime, we now skip testing most compression methods (bzip2,
zlib, lzma) in cloud objstorages by default. Testing all compression
methods can still be done by specifying --all-compression-methods
on
pytest command-line.
