Alex Schultz c6918e5da6 Migrate install to deploy-guide 
The deployment guide is currently pointed at triplo-docs but it has been
requested that we actually publish a deployment guide. This change
extracts many of the installation doc pages and moves them into the
deploy-guide source tree.  Once the deploy-guide is published, we will
follow up to reference the deployment guide from tripleo-docs.

Use whole disk images for overcloud

By default, TripleO overcloud-full image is a partition image. Such images carry only the root partition contents and no partition table. Alternatively, whole disk images can be used, which carry all partitions, a partition table and a boot loader.

Whole disk images can be built with diskimage-builder - see Ironic images documentation for details. Note that this does not affect ironic-python-agent images.

Use the following command to treat overcloud-full as a whole disk image when uploading images:

openstack overcloud image upload --whole-disk

In this case only overcloud-full.qcow2 file is required, overcloud-full.initrd and overcloud-full.vmlinuz are not used.
