Add note about images to README
Update build images REAMDE
update ironic patches
Update REAMDE for build images
update vxlan patch
Default memory size to 3072 MB

We've started defaulting the virt setups to 3 gig vms, but the
instack-deploy-overcloud script still defaults to 2 gig node defs,
which causes deploys to fail because the flavor is defined to
require 3 gig.
Update vxlan cherry-pick

Patch set 8 was broken.  Use patch set 9, which works correctly.
Add deployment-mode to json configuration
Update some other defaults to 3 gig

I only changed the instack-deploy-overcloud value, but it appears
in several other places and will likely cause problems there too.
Pin swift when using LKG=1

The current swift has a change that doesn't work with our other
LKG versions.
export $RCFILE and $ANSWERSFILE
Add imagefactory stuff
update imagefactory stuff
Add initial rhel-7-undercloud-source json file

This needs a bunch of cleanup to remove references to fedora, but
it adds the necessary rdo repo so we can install openvswitch on
rhel7 underclouds.  For the moment that should be enough to enable
undercloud source installs with no hackery.
Set instack vm hostname

It can be confusing if you have multiple machines named 'localhost'
update imagefactory stuff
Allow overriding JSONFILE in instack-install-undercloud-source

We need to be able to point at a rhel7-specific one
Add deploy ramdisk build
Remove DEPLOY_NAME from tdl's, it's superfulous
Don't set the instack vm hostname

It breaks rabbitmq to have the hostname changed.  Would still be
nice to do this, but it will take more than this one line so just
reverting the change for now.
