Ian Wienand ddb06b6657 source-repositories: don't use --git-dir 
A recent(-ish) change in git [1] has exposed a bug in caching that
appears in one very specific circumstance -- updating the
openstack/openstack super-repo [2].

This repo gets a submodule update every time something is pushed.  By
using "--git-dir" while the cwd is one-level above the actual repo we
are confusing [1] which is not finding the submodule directories
correctly and giving us an error:

 Could not access submodule 'foo'

for every submodule that has updated between now and the last time we
updated the cache. [3]

The git manual does warn about this

 If you just want to run git as if it was started in <path> then use
 git -C <path>.

Indeed, that is what we want to do in this path.  Modify the calls to
use -C.

[1] 505a276596
[2] https://opendev.org/openstack/openstack/
[3] The result for opendev production is that image builds fail every
    time an openstack/* project is checked in; we then race to retry
    the build before another commit lands and updates the submodules
    again.

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/
