Patchbot failure metaticket

[mderickx]

The goal of this metaticket is to make it easy to see if there is already a ticket for failures of some patchbots. If a patchbot failure is not on the list, please make ticket with blocker priority for it, if it does not yet exist and add it here together with a list of the affected files!
