Demonstrate how to use Keycloak's admin REST API with a postman client application.

For invoking a REST endpoint, client application should obtain an access token. After that the access token should be added to the authorization header of each REST API call as a bearer token.

OAuth 2.0 protocol is used to obtain access token.
