For authentication, the community recommends the use of keystoneauth1
instead of python-keystoneclient. Therefore, Blazar should follow
this trend and migrate to keystoneauth1.
This patch enables blazarclient to use keystoneauth1 for authentications
and REST API requests and also enables use of project_id, project_name,
project_domain_id, project_domain_name, user_domain_id and user_domain_name
for authentication.
