[velis74]

Adds Middleware.openapi_parameters_for(viewset, action, configuration). route_viewset calls it for each operation it routes, with the middleware's @action_configuration value for that action (ByAction resolved); it returns openapi_parameters. A middleware that does not read its value on some operations (e.g. configured False, or a viewset of its own package) overrides it and returns nothing for them. A function middleware's openapi_parameters attribute still applies to every operation.

Needed by taskwire: TaskwireMiddleware declares X-Taskwire-Token, but calls to taskwire's own viewset are never tracked, so the header does not belong on those operations. Without this, taskwire removes its middleware from settings.viewsets_command_middleware while its viewset is routed (velis74/taskwire#33).

Docs (command middleware guide, route_viewset reference) and CHANGELOG updated; version 0.15.3 for both packages.
