Recent change [1] moved all functional and fullstack tests to be
uploaded in single archive to Swift.
Sometimes, like e.g. in case of the networking-bgpvpn functional
tests, there is no logs directory at all so ansible tasks to prepare
tar.gz archive shouldn't be created at all.

This new role will prepare archive with the logs from all
functional/fullstack tests. It will be more efficient to upload one
archive to swift after tests are done instead of uploading to Swift
many small files with logs from each test.
