This PR adds a new test that automates the above mentioned test case.
It starts the installation in text mode using the `install_text` test
case, which it interrupts using the Anaconda crash trigger.
When the crash happens, it goes through the process of reporting
the bug to Bugzilla, checks that Bugzilla sends a positive
confirmation of the action, but also performs some REST API
calls to do a proper check and then it closes the bug to clean up.
