Use dib-run-parts from dib-utils

Now that dib-run-parts has been moved to the dib-utils project, we
need to update diskimage-builder to use it instead of the version
directly in diskimage-builder.

This change removes the old copy of the dib-run-parts script in
the element, adds dib-utils as a dependency of diskimage-builder,
and updates the uses of dib-run-parts to correctly handle the fact
that it is now external to the project.

Add vmedia boot support for deploy-ironic element

deploy-ironic element currently retrieves token over tftp and
expects BOOT_IP_ADDRESS to be set.  This commit adds support for
retrieving token file from virtual media if node booted from
virtual media. Also corrects the issue for BOOT_IP_ADDRESS not set
for virtual media boot.

Reset yum configuration in post-install.d

When using the yum element, we should reset the changes we've made to
/etc/yum.conf during post-install.d. Otherwise, this build time
configuration is propagated into booted instances.

Run environment.d hook for manifests earlier

15-pip-manifests depends on the variables defined by the manifests
element, so we need to run this one earlier. I would have thought things
were alpha sorted after the numerical sort...but I just ran into this,
so apparently not.

Change order for yum-repos file in centos7 element

Due to changes in centos7 element to use package-installs the order
of yum-repos in pre-install.d needs to be changed, to make yum repos
available before package-installs is called to install packages.
