Isolate license_management ruby from project

* Target ruby version 2.7.1
* Add spec to fetch gems from a custom source
* Add proxy to rubygems.org config
* Specify default env vars to support offline environment
* Cleanup custom certificates after spec
* Inline docker-test script
* Do not install license_finder with each installed ruby
* Increase gem log verbosity and include backtrace
* Extract test fixtures for the different ruby scenarios
* Find *.gemspec files in gems dir
* Use RUBYLIB to hijack src path
* Run scan from project path dir
