The current code always overrides tox_environment when running
functional tests, but the correct behavior is to add
the discovered environment variables to tox_environments,
while keeping the user-specified value for it.
The current behavior breaks the devstack-tox-functional children
jobs, like openstacksdk-functional-devstack-ironic, which set
tox_environment.

The role reads the OS_* variables set by devstack through openrc
for the specified user and project and exports them as
the os_env_vars fact. It is meant to be used as a porting aid
for the jobs of the non-unified *clients only.
This is useful to run functional tests against the generated
environment. A slightly less generic version of this role
is currently used by python-cinderclient and python-novaclient
(get-os-environment).
In order to make this more useful, call it from
devstack-tox-functional and derived jobs. The role
execution is disabled by default and it can be enabled
by setting openrc_enable_export: true.
