Issue while executing “update account metadata”, ”create container metadata”, ”create object metadata” and ”show object metadata"

[Saurabh jangir]

While executing “update account metadata”, ”create container metadata”, ”create object metadata” and ”show object metadata" use case, two different behaviours are seen:
1) when a newly generated token is sent from proxy server to keystone middleware for authentication, keystone middleware delays the authentication and then the proxy server sends the 'HEAD' request to the account server for updating the headers .Proxy server again sends the request to keystone middleware for authentication then keystone middleware confirms the authentication.
2) In another case, the keystone middleware authenticates the token in the first request itself and in this case no request is sent to the account server from the proxy server.
