Added an ability to retrieve information about the current user,
current project, environment owner (both user and project)
from keystone. Appropriate information (including
extra fields but excluding internal system data) is fetched from
Keystone using the same service credentials that are used to validate
tokens, create trusts etc.
- io.murano.User and io.murano.Project classes were added.
- Both classes have 2 static methods to get current and environment
owner object of appropriate class
- Object model now contains project_id/user_id of the user who
created the environment
- Deployment task contains project_id (renamed from tenant_id)
and user_id of the user who initiated the deployment
