    Add HEAD api response for test s3 server BucketHandler

    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
