Workflow to find credentials details from:
1. The environment variables (ENV['OS_*'])
2. If not enough, credentials available from the environment RC file
to be used. Default RC file must be in current user homedir: ~/openrc
- Adds module Puppet::Provider::Openstack::Auth providing class methods for
providers instead of relying on superclass inheritance.
As discussed [1], this purposefully removes the possibility to pass authenti-
cation details as parameters to Puppet resources instances.
- Wraps credentials information with object:
Puppet::Provider::Openstack::Credentials
- The credentials information is used in a withenv block
Review for puppet-keystone needs to be merged at same time:
