Implement project personas in custom placement policy file
Implement project personas in custom placement policy file

This change implements all the project personas for placement, which is
really only two (project-admin and project-reader) since placement is
pretty much isolated to administrator use. There is one API left open to
project readers to get useage.

This file was modified by generating the default sample policy file in
placement:

  $ oslopolicy-sample-generator --namespace placement

Then, working through the file and implement project-admin instead of
the system peresona. After that, I used the
convert_policy_yaml_to_heat_template.py tool to update the existing
defaults in enable-secure-rbac.yaml.
