Move to generic list and details routes

Instead of defining route for each resource, we should have two routes, one for list and another for details

```js
[
  { path: '/c/:cluster/details/:apiName/:namespace?/:name', component: KubeObjectDetails },
  { path: '/c/:cluster/details/:apiName', component: KubeObjectList }
]
```

This will really simplify our routing setup and also allow for easier handling of custom resources
