new a7f4849 CAMEL-16353: camel-main - Add @EagerClassloaded to mark
classes which should be eager loaded via camel-main. This optimize to load
these classes before Camel is started and otherwise would load these classes on
first message processed. A maven plugin scans the code and updates the source
code to keep the list of classes to eager loaded automatic up-to-date.
