response-content-disposition header is not respected

[torrlane]

When retrieving an object, if the url contains the response-content-disposition query parameter, the response should contain the content-disposition header. This makes it easier to provide urls etc... to download attachments.

e.g: http://127.0.0.1:8001/my.bucket.prefix/LPJNul-wow4m6DsqxbninhsWHlwfp0JecwQzYpOLmCQ?response-content-disposition=attachment%3B%20filename%3D%22LPJNul-wow4m6DsqxbninhsWHlwfp0JecwQzYpOLmCQ%22

There are other url query params for customizing the response:

response-content-disposition
response-content-type
response-expires
response-cache-control
response-content-encoding
