Camel 4.9 - Add support for code completion for global data formats

[davsclaus]

You can configure in XML DSL and in YAML DSL now that are outside the routes. This makes it possible to configure them once globally, and then reuse in the routes.

<camel>

    <dataFormats>
        <base64 id="myBase2" lineLength="60" urlSafe="true"/>
    </dataFormats>

    <route>
        <from uri="direct:start"/>
        <marshal><custom ref="myBase2"/></marshal>
        <to uri="mock:result"/>
    </route>

</camel>

Inside <dataFormats> you want code completion for the 50+ data formats that are in Camel and how to configure them.

The same for YAML DSL:

- dataFormats:
  - base64:
      id: df1
      lineLength: 88
  - csv:
      id: df2
      headerDisabled: true
      ignoreEmptyLines: true
