diskimage-builder failed due to "dib-run-parts: command not found" in Bare Metal Service Installation Guide

[Naohiro Tamura]

The following diskimage-builder command failed due to "dib-run-parts: command not found".
This step is described in "Image Requirements" section, Bare Metal Service Installation Guide.
http://docs.openstack.org/developer/ironic/deploy/install-guide.html#image-requirements

Steps to reproduce:
-----------------------

1. execute the script tripleo-incubator provides
naohirot@ubuntu2:~/work/image$ export TRIPLEO_OS_DISTRO=ubuntu
naohirot@ubuntu2:~/work/image$ export TRIPLEO_OS_FAMILY=debian
naohirot@ubuntu2:~/work/image$ bash ./install-dependencies

2. execute diskimage-builder
naohirot@ubuntu2:~/work/image$ git clone https://github.com/openstack/diskimage-builder.git
naohirot@ubuntu2:~/work/image/diskimage-builder$ cd diskimage-builder
naohirot@ubuntu2:~/work/image/diskimage-builder$ bin/disk-image-create ubuntu baremetal -o my-image
Building elements: base ubuntu baremetal
Expanded element dependencies to: dib-run-parts manifests baremetal cache-url pkg-map base ubuntu cloud-init-datasources dpkg dkms
Not enough RAM to use tmpfs for build. (4048236 < 4G)
Building in /tmp/image.UYgqyc4M
/home/naohirot/work/image/diskimage-builder/bin/../lib/common-functions: line 184: dib-run-parts: command not found
umount2: Invalid argument
umount: /tmp/image.UYgqyc4M: not mounted
umount2: Invalid argument
umount: /tmp/image.Cp19OLoj: not mounted

Analysis:
---------
diskimage-builder requires dib-utils.
It worked after having installed dib-utils.

naohirot@ubuntu2:~/work/image$ git clone https://github.com/openstack/dib-utils.git
naohirot@ubuntu2:~/work/image$ (cd dib-utils; ./setup.py build; sudo ./setup.py install)
naohirot@ubuntu2:~/work/image/diskimage-builder$ bin/disk-image-create ubuntu baremetal -o my-image

    Replace DIB installation step from git clone to pip

    This replaces DIB installation step from git clone to pip
    in Bare Metal Service Installation Guide so that all of DIB required
    packages such as dib-utils can be installed automatically.
    Without this change, diskimage-builder command fails due to
    "dib-run-parts: command not found".
    The install-dependencies script which tripleo-incubator provides
    doesn't install all of DIB required packages.
