Ian Cordasco 7562ab3e3a Refactor shell unittests and add hosts shell tests
This refactors our shell unittest helpers into three base classes for
further unit test classes to subclass and extend. This also corrects
some problems with the hosts shell parameters that either didn't
previous work or were wrong and no longer belong. Finally, it removes
project_id from places where it no longer belongs.
