1. Fixed issue 'cvc-complex-type.3.2.2: Attribute and customize brokerName

Hi,

    'activemq' service doesn't start because of the 'destroyApplicationContextOnStop' on 'broker' element in 'activemq.xml.erb' template. 'activemq' service throws below error in the error log '/opt/apache-activemq-5.9.1/data/activemq.log'.

   This issue had been fixed by removing 'destroyApplicationContextOnStop' attribute from the 'broker' element.

   'ChefSpec' and 'ServerSpec' tests have been executed and both are successful.
