Add two undeclared dependencies to the Dockerfile

While auditing our dependencies in antipiation of DIB elements being
created, I found these dependencies not being explicitly installed by
docker. We should explicitly install them even if we expect them to
exist in the base image.

Change-Id: I38ec7167ae24b9abbda08cbbbdd55205612b7288
Add support for psutil v1 as well as v2

Openstack global requirements updated to specify version 1 only, and we
only supported version 2.

Bump CoreOS to latest stable

Two reasons:

1) Use a build that is marked stable
2) Fixes an issue where boot hangs for minutes on updating CA
   things, which enables much faster deploy times.

Bump IPA container to use Trusty

Bump IPA container to use trusty. This gives us a newer version of pip
which is required to install newer requirements that are packaged as
wheels.

Only other change to dockerfile is to ensure python 3 is
removed, in order to avoid raising the size of the container. After this
patch, the agent image goes up in size 3M, which is managable.

Updated from global requirements

Prevent python 2.7 from being purged in container

Python 2.7 is being removed, somehow, despite python3 being specified.
This should fix the issue and make the container usable again.

Clean up image build script

This change allows the image build script to support the existing
jobs that build images for distribution, as well as future jobs that
build the image within devstack for testing.

Add vmedia boot support in IPA

This commit adds support for booting IPA from virtual
media cdrom.  When IPA is booted over virtual media cdrom,
the parameters to the IPA are passed in a text file within
the virtual media floppy.

Fix incorrect documentation

Two changes, first is that we now upload individual files instead of a
tarball of both. The other is a catch from Jim to properly use building.

Fix minor documentation issues

I updated the URL to point to the correct path to the uploaded IPA
ramdisk, as well as adding a note about running IPA inside Virtual
Media.

Add missing "/files" to IPA image URLs

Corrects a 404 error when visiting these URLs.

Fix exception that is not properly raised

This commit fixes an exception that was not properly raised, and
also makes the exception more relevant.

This also fixes an outstanding bug where, if the agent
was not associated with a node, get_node_uuid() would fail in an
unexpected manner.
