Normalize labels based on the internal mapping

[blakeli0]

We recently had an issue that it was already triaged and assigned a label(testing), but still showed up in our un-triaged list. This is because testing is not considered a proper label in the filter, we need to
normalize the labels based on the internal mapping so that the github labels are correctly recognized by buganizer.
We can start with adding labels like type: process, type:question etc.
