Nested Properties in Camel Routes

Apache Camel does not support Spring's nested properties in its configuration. I believe this feature is coming up, but at the time of writing this it's neither the case in the version we're running (2.9.1) nor in the current version (2.10.6 seemed totally broken, 2.10.5 also doesn't support it). This is generally unfortunate but in our case we're particularly missing this feature for the autoStartup property of a route.

We usually have groups of routes that are either started together or not at all. However, for e.g. debugging it would be nice to turn the whole group off and specific routes in the group on. This can be achieved relatively easily with a simple helper class that gets properties injected by Spring, hence supporting nested properties.
