Just setting CloudDomain won't make the domains used consistent.
There are a number of CloudName parameters that must be set as well.
This change adds a sample environment that includes all of those
parameters so it is easy to set everything consistently.
Also fixes the description of CloudNameCtlplane to reflect the
actual use for that parameter.
This is a tool to automate the generation of our sample environment
files. It takes a yaml file as input, and based on the environments
defined in that file generates a number of sample environment files
from the parameters in the Heat templates. A tox genconfig target
is added that mirrors how the other OpenStack services generate
their sample config files.
A description of the available options for the input file is
provided in a README file in the sample-env-generator directory.
In this commit only a single sample config is provided as a basic
example of how the tool works, but subsequent commits will add
more generated sample configs.
