"""
This script will generate the etc/tempest.conf file by applying a series of
specified options in the following order:
1. Values from etc/default-overrides.conf, if present. This file will be
provided by the distributor of the tempest code, a distro for example, to
specify defaults that are different than the generic defaults for tempest.
2. Values using the file provided by the --deployer-input argument to the
script.
Some required options differ among deployed clouds but the right values cannot
be discovered by the user. The file used here could be created by an installer,
or manually if necessary.
3. Values provided on the command line. These override all other values.
4. Discovery. Values that have not been provided in steps [2-3] will be
obtained by querying the cloud.
