JobScheduler configuration files can contain extension elements

Some configuration elements can contain additional XML element <extensions>.
Under this, any additional information can be stored that are not directly part of the configuration of the JobScheduler core.

Currently below the <extensions> element specifying elements from the namespace of JOE provided.

A job with this element, for example, could look like this.

 
<job order="no" stop_on_error="no">
  <extensions>
    <joe xmlns="www.sos-berlin.com/schema/joe">
    <author>someone</author>
    </joe>     
  </extensions>
    <script language="shell">
        <![CDATA[
echo hello world
        ]]>
    </script>
    <run_time/>
</job>

Currently, the indication of <extensions> element for the following JobScheduler configuration elements are permitted:

• <config>
• <job>
• <job_chain>
• <job_chain_node>
• <order>
• <process_classes>
• <schedules>
• <locks>
