* Error if shade is too old for domain_id on os_project
os_project's domain_id parameter requires shade >= 1.8.1 to work. Be
explicit.
Fixes#2805 os_project requires python-shade 1.8.1 or higher
* What I really meant was 1.8.0
The os_project module instantiates the openstack cloud object
by passing the module params kwargs.
As the params contain a key named 'domain_id', this is used
for domain in the OpenStack connection, instead of the domain value
the user specifies on the OSCC clouds.yaml or OpenStack envvars.
This fix corrects this by popping the 'domain_id' key, so it we
keep the value but it's not passed later on module.params.
