The job JobSchedulerPLSQLJobJSAdapterClass should return parsed out parameters to the task parameters

Current Situation

The job JobSchedulerPLSQLJobJSAdapterClass can parse the dbms output with the regex in variable_parser_reg_expr e.g. ^SET\s+([^\s])\s*IS\s(.*)$
That means that an output like

DBMS_OUTPUT.PUT_LINE('SET myParam ' || FIELD);

should create a task parameter myParam with the value of FIELD.
This task parameter should be available in the postprocession script like
{{ var 'XXX' = spooler_task.params.value( 'myParam ' );}}

The task parameter myParam is not available in the postprocessing script

This issue comes with YADE-522

Desired Behavior

When setting the output with DBMS_OUTPUT.PUT_LINE('SET myParam ' || FIELD);
to SET myParam=value the task parameter myParam should be available in the postprocessing script
