**NOTE TO REVIEWER** Please review only the last commit as it depends on
#11174
This is the third (and not last) part of making the Production
image more corporate-environment friendly. It's been prepared
for the request of one of the big Airflow user (company) that
has rather strict security requirements when it comes to
preparing and building images. They are committed to
synchronizing with the progress of Apache Airflow 2.0 development
and making the image customizable so that they can build it using
only sources controlled by them internally was one of the important
requirements for them.
This change adds the possibilty of customizing various steps in
the build process:
* adding custom scripts to be run before installation of both
build image and runtime image. This allows for example to
add installing custom GPG keys, and adding custom sources.
* customizing the way NodeJS and Yarn are installed in the
build image segment - as they might rely on their own way
of installation.
* adding extra packages to be installed during both build and
dev segment build steps. This is crucial to achieve the same
size optimizations as the original image.
* defining additional environment variables (for example
environment variables that indicate acceptance of the EULAs
in case of installing proprietary packages that require
EULA acceptance - both in the build image and runtime image
(again the goal is to keep the image optimized for size)
The image build process remains the same when no customization
options are specified, but having those options increases
flexibility of the image build process in corporate environments.
This is part of #11171.
This change also fixes some of the issues opened and raised by
other users of the Dockerfile.
Fixes: #10730
Fixes: #10555
Fixes: #10856
Input from those issues has been taken into account when this
change was designed so that the cases described in those issues
could be implemented. Example from one of the issue landed as
an example way of building highly customized Airflow Image
using those customization options.
Depends on #11174
