The admin config resize doc was linking to a now non-existent user guide doc which was deleted in pike. This change imports the resize user guide from the openstack-manuals stable/ocata branch, fixes the link, and updates the resize user doc to (1) link to our internal shutdown_timeout config option reference and (2) link to the image properties doc in glance for the os_shutdown_timeout image property.

Configure resize
Resize (or Server resize) is the ability to change the flavor of a server, thus allowing it to upscale or downscale according to user needs. For this feature to work properly, you might need to configure some underlying virt layers.
This document needs to be updated for other virt drivers, shared storage considerations, etc.
KVM
Resize on KVM is implemented currently by transferring the images between compute nodes over ssh. For KVM you need hostnames to resolve properly and passwordless ssh access between your compute hosts. Direct access from one compute host to another is needed to copy the VM file across.
Cloud end users can find out how to resize a server by reading /user/resize.
XenServer
To get resize to work with XenServer (and XCP), you need to establish
a root trust between all hypervisor nodes and provide an
/image mount point to your hypervisors dom0.
