routing: Simplify how routes are defined. * No more declaring the type of route parameters -- the sources and generators already know what type each parameter is supposed to be. * Same for variadic parameters -- we know already. * Update cache version to force a clear reload of the config. * Update tests. TODO: simplify code in the `Route` class to use source or generator transparently.
