xenserver: Add "reload" and "force-reload" support to init script.

I can't easily find anything that documents what commands Fedora init
scripts should support, but many of them support "reload" and
"force-reload". This commit adds support for them to the XenServer init
scripts.  (The Debian init scripts already had support.)

Debian does document that reload and force-reload should be supported:

Bug #3266.
