Description of problem:
In System Settings page in RHQ 4.12 (equivalent of JBoss ON 3.3.5) there are two new parameters: PARTITION_EVENT_PURGE and RESOURCE_CONFIG_HISTORY_PURGE. These parameters are mandatory but by default their value is not set. Also, although, we can assume what the meaning of these parameters are, there are no description on the page. 

When setting both parameters to 1 - I assumed that all partition events older then a day would be deleted. However, this is not a case. 

Version-Release number of selected component (if applicable):
RHQ 4.12

How reproducible:
Always

Steps to Reproduce:
1. Install RHQ
2. Navigate to RHQ UI -> Administration -> System Settings and set PARTITION_EVENT_PURGE and RESOURCE_CONFIG_HISTORY_PURGE to 1;
3. Save newly added values (having in mind a workaround from the Bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1290436);
4. Wait for the Data Purge Job;

Actual results:
Nothing has been deleted. To confirm this, navigate to RHQ UI -> Administration -> Partition Events and confirm that the Total Rows number is not changed;

Expected results:
All events older then a day are deleted.
