[Users] Native Ploop Support in 7.0.11

[Jonathan Wright]

I noticed this line in the changelogs:

---
Native discard support in ploop enabling automatic discard requests on 
all ext4 filesystems over ploop block devices, except containers running 
on Virtuozzo Storage.
---

How do we go about enabling this?  It doesn't seem to be enabled by 
default as part of the update.  Is it the "--autocompact" flag for 
prlctl set?  If so, this doesn't appear to add/modify anything in 
ve.conf.  If this is the correct setting, where is it actually set, ie 
how could this be changed aside from the --autocompact flag?
