incorrect response code from v2 delete image member call

[Brian Rosmaita]

Currently on success, DELETE /v2/image/{imageId}/members/{memberId} returns 200 with no response body.

According to the Glance API contract, a 200 means you should expect a response body. Success with no response body should be 204.

    Change response code for successful delete image member to 204.

    The delete image member call currently returns 200 with no response
    body. According to the API contract, 200 means to expect a body.
    This patch changes the response code to 204.
