Problem/Motivation
In #1857256: Convert the taxonomy listing and feed at /taxonomy/term/%term to Views
it became clear that in some rare cases (you are a module developer) you want to provide a route
prefixed with your module. If you use yml files you can control the route name, so you put it prefixed with your name. In case you never actually
want to write code for yourself but just let views take care about it, you need a way to control that routename.
Proposed resolution
This patch adds a little textfield into the views UI that allows to specify the used route name. By default though views still generates a route name like "views.$view_name.$display_id".
