Search Test Runs via Env properties and display progress

[atodorov]

This change makes it possible to search Test Runs by environment properties and also improves the progress bar shown next to each run in the search results. We show the completion result in % and also show a red bar if there are failed cases.

100% means everything was tested, all blue means none of the tested cases failed!
