When using the customizable filter to modify variables, if a template
overrides file is shared between multiple sets of images, it is sometimes
possible that a customised variable does not exist for a set of images.
A specific example:
My template overrides file has this:
{% set ironic_inspector_packages_append = ["python-pip"] %}
Normally I build binary/centos images.
kolla-build -t binary
Sometimes however I build a bifrost centos/source image, because bifrost
does not support binary images.
kolla-build -t source bifrost
The ironic inspector image does not define ironic_inspector_packages for
the source build, since it does not need any.
{% elif install_type == 'source' %}
{% if base_distro in ['debian', 'ubuntu'] %}
{% set ironic_inspector_packages = ['iptables'] %}
{% endif %}
{{ macros.install_packages(ironic_inspector_packages |
customizable("packages")) }}
The install_packages macro copes with the undefined variable, however
the customizable filter does not handle the base variable being
undefined if a customised example exists.
This change allows the customizable filter to ignore undefined
variables, even if they have been customised.
