Pivotal SSO tile now includes a management API

[TimHess]

Now that the SSO tile has an API, we may be able to script the setup for any samples that use it https://docs.pivotal.io/p-identity/sso-api/#introduction

[cf-gitbot]

We have created an issue in Pivotal Tracker to manage this:

https://www.pivotaltracker.com/story/show/163389902

The labels on this github issue will be updated when the story is started.

Also update samples to use the resource.action naming convention for scopes and modify manifests to leverage SSO specific environmental variables to precreate resources during cf push
