Camel K modelines support

• completion and hover for:
  • option names
  • trait definition names
  • trait property names
  • Camel artifact id for dependency
  • mvn dependency
  • Camel properties
  • diagnostic for duplicated trait properties

Note: By default, the completion is using the Camel cased notation. But It is possible to use dashed notation in the properties file and Camel K modelines. It is using the dashed notation when there is another Camel property already using the dashed notation in the same file.
