getRoutesByPath: Filter the routes by path

[sinkcup]

$ php artisan route:list --help

Options:
      --method[=METHOD]    Filter the routes by method
      --name[=NAME]        Filter the routes by name
      --path[=PATH]        Filter the routes by path

route command has 3 filters, but only 2 in code:

Route::getRoutes()->getRoutesByMethod();
Route::getRoutes()->getRoutesByName();

suggestion: support getRoutesByPath: Filter the routes by path

Route::getRoutes()->getRoutesByPath();
