Custom quartz.properties file is not loaded for SwitchYard Quartz binding in FSW 6

Issue

• We are using Quartz scheduler binding. The issue is, we cannot change the default Quartz properties.
• When a quartz scheduler being triggered, there are by default 10 threads spawned to do the task. We want to limit the number of threads that Quartz uses to something like "org.quartz.threadPool.threadCount = 1".
• However, the default quartz.properties in the Quartz jar is used even if a custom properties file is in our module.
• Our switchyard.xml is as follows:

    <sca:service name="SampleTimer" promote="SampleTimerBean/SampleTimer">
      <sca:interface.java interface="com.example.switchyard.app.SampleTimer"></sca:interface>
      <quartz:binding.quartz name="sampleTimer">
        <sy:operationSelector operationName="sampleOp"></sy:operationSelector>
        <quartz:name>sampleTimer</quartz:name>
        <quartz:cron>* */15 * * * ?</quartz:cron>
      </quartz:binding.quartz>
    </sca:service>
