### Current Behavior Bug : Apisix converts reponse content types to plain/text Testing with local apisix & test api server env (apisix on 9080 port , test api server with 8000 port ) - Json response if request sended directly to test api server <img width="580" alt="image" src="https://user-images.githubusercontent.com/26168539/203670033-dde8de39-8bc6-4019-9a4b-2f263f4146c5.png";> - Converted to plain/text if request sended via apisix upstream  Cause many type of api servers handled by apisix, some of them don't handle http response with json automatically, I expecting apisix not to convert response types to text/plain. Any approach or opinion will be appreciated to fix this problems ### Expected Behavior Content type must be consist after handled by apisix upstream. ### Error Logs This seems to logical problem with apisix core, so no error logs included ### Steps to Reproduce 1. send request to upstream via apisix server with Content-types: application/json header 2. check content types converted to plain/text  ### Environment - APISIX version (run `apisix version`): 2.99 - Operating system (run `uname -a`): RHEL 8 - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): 1.21.4 - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): 3.5.4 - APISIX Dashboard version, if relevant: 2.13.0 - Plugin runner version, for issues related to plugin runners: java 17 - LuaRocks version, for installation issues (run `luarocks --version`): 5.4.4 -- This is an automated message from the Apache Git Service.
