Description of problem:

I created and edited several disks and added the wipe after delete tag. 
although the parameter is updated and if we delete the disk is sent to vdsm, it is not saved in UI after we press OK (this is not a timeout issue since I waited several minutes and even logged in and out). 

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

si15

How reproducible:

100%

Steps to Reproduce:
1. create/edit a disk and check the "wipe after delete" check box -> press OK
2. check backend log -> the update is saved
3. edit the disk -> the wipe after delete is not checked. 
4. remove the disk and look for /dev/zero in vdsm log
  
Actual results:

although the option is saved in db and sent to vdsm when we remove the disk the UI is not saving the check box on wipe after delete. 

Expected results:

wipe after delete should be checked

Additional info: logs


I also tested what will happen when my default is wipe after delete. 
it seems that although the check box is marked as checked when we create the disk once we press ok and create the disk the check box disappears. 



when disk is deleted we can see in vdsm log that its is sent as post zeroing: 

root@gold-vdsd ~]# tail -f /var/log/vdsm/vdsm.log |grep /dev/zero

backend log shows that the disk is updated:
