[CAMEL-17310] Add dev goal to enable live reloading

[Croway]

As discussed in https://issues.apache.org/jira/browse/CAMEL-17310 there are some issues with live reload, I'll try to investigate more

[davsclaus]

The fileWatcherDirectory was the old name, we can give it a better and shorter name.

Also I think the plugin should default to reload automatic, and automatic select the src/main/resources directory.
There is a way via a maven plugin to get hold of "resource directory" but I guess that 99% its always src/main/resources anyway.

For java routes then its a bit more tricky as they would be in src/main/java. So we can in the future have some kind of watcher that automatic detects all .java source files and whether they are Camel routes.

Thanks, I have implemented your comment, moreover I had to do some changes to RouteWatcherReloadStrategy in order to handle recursive live reload, and I did some changes in case of file removal.
