Set up issue templates to reduce wrongly filed bugs
Issue templates are markdown files that pre-fill a bug report with some information, guiding the reporter into a given structure and/or suggesting required information to be attached in the original report. See the gitlab doc and as example the libinput Bug template.
Using those for the wayland repo may reduce the number of compositor issues filed against the wayland repo, we should add the comments and/or a link explaining what the repository is and that it doesn't fix whatever bug the user is about to file :)
