wjunlu 864ae11509 Append detailed printing information when exec_sudo fails 
This patch tries to add more detailed info by appending
error output to exec_sudo print.

In current implementation, only a simple static note `Exception:
exec_sudo failed` is printed:
```
INFO diskimage_builder.block_device.utils [-] Calling [sudo sgdisk
 /tmp/dib_image.jZaDPxtX/image0.raw -n 1:0:+550M -t 1:EF00 -c 1:ESP
 -n 2:0:+8M -t 2:EF02 -c 2:BSP -n 3:0:+2077M -t 3:8300 -c 3:root]
ERROR diskimage_builder.block_device.blockdevice [-] Create failed;
 rollback initiated
// ... ...
diskimage_builder.block_device.exception.BlockDeviceSetupException:
 exec_sudo failed
```

but the root reason is missing. We can’t get more error info to
make sure what the real root reason even a simple problem like
`command not found`, we have to reproduce locally and manually.

After this patch, the error message like:
```
INFO diskimage_builder.block_device.utils [-] Calling [sudo sgdisk
 /tmp/dib_image.jZaDPxtX/image0.raw -n 1:0:+550M -t 1:EF00 -c 1:ESP
 -n 2:0:+8M -t 2:EF02 -c 2:BSP -n 3:0:+2077M -t 3:8300 -c 3:root]
ERROR diskimage_builder.block_device.blockdevice [-] Create failed;
 rollback initiated
// ... ...
diskimage_builder.block_device.exception.BlockDeviceSetupException:
 exec_sudo failed: sudo: sgdisk: command not found
```
We can easily find the real problem and solve it.

Closes-Bug: #2024980

Image building tools for OpenStack
==================================

``diskimage-builder`` is a flexible suite of components for building a
wide-range of disk images, filesystem images and ramdisk images for
use with OpenStack.

This repository has the core functionality for building such images,
both virtual and bare metal. Images are composed using `elements`;
while fundamental elements are provided here, individual projects have
the flexibility to customise the image build with their own elements.

For example::

  $ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu

will create a bootable Ubuntu Bionic based ``qcow2`` image.

``diskimage-builder`` is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of `TripleO <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images. They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<https://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.

Full documentation, the source of which is in ``doc/source/``, is
published at:

* https://docs.openstack.org/diskimage-builder/latest/
