Handle case insensitivity when processing HTTP response headers for Autorest Java #1272
Description
Cognitive Services recently enabled HTTP/2.0 in APIM. Unlike HTTP/1.1 which states that clients/servers should treat the headers in a case-insensitive way, HTTP/2.0 requires all headers to be in lower-case.
It breaks the current behavior, specifically for the Computer Vision Track 1 SDK since the client code (OkHTTP) directly uses the latest available HTTP protocol but does not process the response headers in a case insensitive way resulting in an NPE.
It would help if autorest java could handle the HTTP response headers in a case-insensitive manner.

Sameeksha Vaity (@samvaity) it would be great to document the bug noticed in Computer Vision and capture the gist of the discussion in this issue.

Closing as the design for a while has been to consume
HttpHeadersand pull them out using case-insensitive retrieval, rather than the old design that used a special Jackson ObjectMapper with case-insensitive property name matching.
