ubuntu: Add options to ignore mirror components and use insecure repos

Browse Source 
When using the upstream cloud images with the "ubuntu" element, they
have universe and multiverse enabled which we don't mirror.

To use the infra mirrors as a DIB_DISTRIBUTION_MIRROR with this
element, we need to be able to skip redirecting to universe and
multiverse, and additionally enable insecure repos (as we don't gpg
sign our mirrors).

Add and document two new variables with the ubuntu element to do this.
This is then setup by the openstack-ci-mirrors element so that we use
local mirrors duing dib functional testing for the "ubuntu" element.

@ -11,5 +11,15 @@ Overrides:
* To download a non-default release of Ubuntu cloud images, use the
environment variable ``DIB_RELEASE``. This element will export the
``DIB_RELEASE`` variable.
* Use ``DIB_DISTRIBUTION_MIRROR`` to override the ``sources.list``
with an alternative mirror
* Setting ``DIB_DISTRIBUTION_MIRROR_UBUNTU_IGNORE`` to an
extended-regexp (i.e. the argument to the ``=~`` bash comparitor)
which, when matched, will *not* set that line to the
``DIB_DISTRIBUTION_MIRROR``. For example, if your local mirror
does not mirror the universe and multiverse components, set this to
``(universe|multiverse)``
* Setting ``DIB_DISTRIBUTION_MIRROR_UBUNTU_INSECURE`` updates apt
settings to allow insecure/unuthenticated repositories.
