Permit using arbitrary PyPI urls.

The pypi element is cool, but some folk have local network mirrors
which we should permit them to use.

Inject a PyPI mirror
====================
Bind mounts a PyPI mirror from ~/.cache/image-create/pypi/mirror into the build
environment and temporarily overwrites /root/.pip.conf and .pydistutils.cfg to
use it.
Use a custom PyPI mirror to build images. The default is to bind mount one from
~/.cache/image-create/pypi/mirror into the build environment. The element
temporarily overwrites /root/.pip.conf and .pydistutils.cfg to use it.
When online, the master pypi index is supplied as an extra-url, so uncached
dependencies will still be available. When offline, only the mirror is used - a
stale mirror will cause build failures.
When online, the official pypi.python.org pypi index is supplied as an
extra-url, so uncached dependencies will still be available. When offline, only
the mirror is used - be warned that a stale mirror will cause build failures.
To use an arbitrary mirror set PYPI\_MIRROR\_URL=http[s]://somevalue/
[jeepyb](https://git.openstack.org/cgit/openstack-infra/jeepyb) can be useful in making a
partial PyPI mirror suitable for building images. For instance:
