The aws-sdk-java library was observed sending DELETE requests with a
Content-Type of "application/x-www-form-urlencoded; charset=utf-8".
If we allow that through, SLO will pass it along to the bulk-deleter,
which will respond with:
HTTP/1.1 200 OK
[various headers...]
Number Deleted: 0
Number Not Found: 0
Response Body:
Response Status: 406 Not Acceptable
Errors:
...and nothing will have been deleted. Worse, since the real error code
is buried in the body, it's difficult to detect the underlying cause.
Now, we'll just drop any content-type we receive from the client.
Another patch will be submitted to do something similar for SLO, but
this will fix multi-part deletes for older versions of Swift.
