Problem/Motivation
As we realized on #1851086: Replace admin/people with a View is that overriding existing paths in views is problematic.
Therefore selecting routes by pattern is helpful to allow altering of existing views.
Proposed resolution
Extend the RouteProviderInterface which to include a getRouteByPattern method.
Remaining tasks
DO IT, WRITE TEST, HOPE IT ACTUALLY WORKS
User interface changes
NON
API changes
Extends the interface
