Most REST clients will encapsulate an internal HTTP client object that needs a close call for proper garbage collection. If the client application is using a pool of Azure objects/connections, is there a way to make sure we can force a "close"? For ex: azureInstance = Azure.configure().withLogLevel(HttpLoggingInterceptor.Level.NONE).authenticate(credentials).withDefaultSubscription(); is there a need for azureInstance.close()?
