Feature/test reports custom parametrization

[Angelthree95]

• Added annotation for test parametrization (case ID, product ID, plan ID).
• Added more config options to tcms.conf file.
• Added TODO markers for missing tests

Tested on private TCMS instance, but I can reproduce the results if given time/sample project.
