Current nova test s3 server lacks HEAD for BucketHandler. And it becomes an issue for Boto after version 2.25.0 [1], which changes underlying implementation of get_bucket method from GET to HEAD request. This change fixes this gap by adding HEAD response to test s3 server. And also added cases for testing bucket existence per Boto document suggestion[2], which applies for both Boto prior to or after version 2.25.0 [1] http://docs.pythonboto.org/en/latest/releasenotes/v2.25.0.html [2] http://docs.pythonboto.org/en/latest/s3_tut.html#accessing-a-bucket Change-Id: If992efa40f7f36d337d1b9b1f52859aa0ae51874 Closes-bug: #1277790
