lxd server guide section

[Serge Hallyn]

Hi,

I think I'm done for the moment.  What I have is in lxd.md in
markdown format at:

https://git.launchpad.net/~serge-hallyn/+git/lxdserverguide

(I use the markdown firefox extension to view it)

I'll be out the rest of the week, but comments or patches would
be very welcome.  Particularly from anyone not too familiar with
lxd looking at this with fresh eyes.

thanks,
-serge
