INT-3488: Map `Content-Disposition` HTTP header

JIRA: https://jira.spring.io/browse/INT-3488

In addition map all standard HTTP Headers

The `Transfer-Encoding` has been remained as unmapped
This was removed via INT-2524; a subsequent commit (INT-2744) added a capability to suppress inappropriate response header mapping.

I think we should uncomment this and add it to `HTTP_RESPONSE_HEADER_NAMES_INBOUND_EXCLUSIONS`.

However, I am not convinced that many of these headers should be mapped - consider the proxy use case.

I am leaning towards just solving the reported problem rather than adding all these headers to the mapping.
