Remove log compression before upload
Remove log compression before upload

From #openstack-infra:
fungi> jrosser: there was a necessary change in handling of
compressed log files, jobs should not compress logs on their
own now if you want them to be viewable in a browser (this
was to solve a problem where tarballs were getting silently
decompressed on download without changing their filenames to
drop the .gz extension)
