GitLab

* Integrated 'go.bug.st/testsuite'

It doesn't make much sense to keep it separate in a different library

* Do not use shared download dir for 'cache clean' command tests

* Added method to get cli download dir

* Create infra for sharing directories between tests

* Slighlty improved test output

* Non-parallel testing is no longer required

* Add more time to complete tests

* Update internal/integrationtest/cache/cache_test.go
