We have a good pattern of namespacing env vars with DIB_. Add support
for DIB_PYPI_MIRROR_URL* and maintain backwards compat support.

Using only a local filesystem mirror could lead opaque errors.
Print a warning message in this situations.

Closes-Bug: #1297948
We check python files with dib-lint rather than flake8 which have
conflicting opinions. This means weve been (forcibly) writing non pep8
python.
Also fixing pep8 issues so tests pass.

pypi-mirror creates a separate mirror index for wheels (one per OS
that mirrors are built on). To be able to use it one then needs to be
able to export multiple mirrors for inclusion in pip.conf. As a drive
by I made it possible to disable the use of the pypi.python.org index
without using --offline (as --offline has larger impact).

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

Using a custom pypi mirror can be very convenient, making image builds
substantially faster - because we create multiple virtual
environments we benefit more than single-virtualenv users would.
