[library] heat is using deprecated keystone params

[Alex Schultz]

Warning: Scope(Class[Heat]): The keystone_host parameter is deprecated. Please use auth_uri and identity_uri instead.
Warning: Scope(Class[Heat]): The keystone_port parameter is deprecated. Please use auth_uri and identity_uri instead.
Warning: Scope(Class[Heat]): The keystone_protocol parameter is deprecated. Please use auth_uri and identity_uri instead.

We need to update our usage of the heat module to use the auth_uri and identity_uri instead of the keystone_{host,port,protocol} parameters.
