[keycloak-user] how to implement SSO among services with Keycloak

[Bill Burke]

The demo app shows how this is done:

1. visit customer portal
2. customer portal initiates a login
3. customer portal receives a token
4. customer uses token to make secure REST invocation to another 
database service.
