Untangle tests (#112)

* Isolate S3 test case

* Isolate webdav test case

* Isolate SSH test case

* Isolate local storage test case

* Isolate gpg test case

* Add missing volume mount

* Fix file locations for local test case

* Remove compose test case, use utils

* Use test utils throughout

* Use dedicated tmp dir

* Fix link location that is being tested

* Use dedicated tmp_dirs when working on host fs

* Force delete artifact

* Fix expected filename

* Provide helpful messages on failing tests

* Fix filename

* Use proper volume names

* Fix syntax error, use large resource class

* Use named Docker volumes when referencing them in test scripts

* Add name of test case to logging output
