[Sahara] Hadoop options are not displayed on nodegroup template details page

[Andrew Lazarev]

Steps to reproduce
1. Start creation of hadoop1 nodegroup template
2. Select tasktracker process
3. Set "mapred.child.java.opts" option to "-Xmx201m"
4. Click 'Create'
5. Click to template name to get nodegroup template details
6. Go to 'service configurations'

Observed behavior:
Page displays that "mapred.child.java.opts" parameter is overwritten, but doesn't display value (see screenshot attached).
Manual request to sahara shows that sahara returns correct value. So, problem is on horizon side.
