…ame and empty-token handling Serialize the echoed request continuation token as <ContinuationToken> (previously <continueToken>) so S3 SDK clients populate response['ContinuationToken'] instead of hitting a KeyError. Treat an empty continuation-token as no token: list from the start with IsTruncated=false and echo the empty token back, instead of throwing InvalidArgument when decoding it. Fixes ceph s3-tests test_bucket_listv2_continuationtoken, test_bucket_listv2_continuationtoken_empty and test_bucket_listv2_both_continuationtoken_startafter.

What changes were proposed in this pull request?
ListObjectsV2 has two server-side bugs around the continuation token that make S3 SDK clients fail:
<continueToken>instead of AWS's<ContinuationToken>. botocore maps response fields byelement name, so
response['ContinuationToken']was never populated and clients that read itback hit a
KeyError.ContinuationToken=''was passed(non-null) into
ContinueToken.decodeFromString(), which found no separator and threwInvalidArgument. AWS treats an empty continuation token as no token — return all keys,IsTruncated=false, and echo''back.To align with AWS S3:
ContinuationToken(ListObjectResponse@XmlElement).BucketEndpoint, treat a null/emptycontinuation-tokenquery param as absent (list fromthe start, keyed off the decoded token) while still echoing the request value back.
