vserver to apply settings without reboot.

[ITG]

It would be nice for the vserver module to allow you to update a client's vserver without rebooting their vps.

For instance, if i want to upgrade diskspace, or ram, i can do this from the command line via

(assume 101 as vps id)

vzctl set 101 --physpages 1024M:1024M --save

or upgrade diskspace

vzctl set 101 --diskspace 40G:40G --save

The above commands would apply the new settings to the vps without the need to restart the vps, and would also save those settings to the config file.
