Remove unnecesssary nova constructor calls in each manager API call path
auth.authenticate() creates a nova client object. This nova client
object is never reused introducing a 40msec penalty for each API call.
The heat-api-cfn module authenticates incoming requests. In a
properly secured environment (one where RPC is secured), the
auth.authenticate() calls serve no purpose.
