help request: integrate apisix with wso2 management

### Description

Hi Team,
I’m looking to integrate Apache APISIX Gateway with WSO2 API Manager. APISIX is running in one Kubernetes cluster, and WSO2 APIM is deployed in another cluster. Both clusters are connected via the same Transit Gateway network. What’s the recommended approach for integrating them for API management and runtime traffic? Please provide the recommended approach and any related docs will use for me. Or is there any agent to run separately to integrate with wso2. please help on this, planning for production. Thank you.

### Environment

- APISIX version (run `apisix version`):
- Operating system (run `uname -a`):
- OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
- etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
- APISIX Dashboard version, if relevant:
- Plugin runner version, for issues related to plugin runners:
- LuaRocks version, for installation issues (run `luarocks --version`):

首先审查所描述的 APISIX 和 WSO2 部署，包括独立的 Kubernetes 集群和共享的 Transit Gateway 网络。一个有用的成果应是形成文档化的、面向生产环境的集成指南，涵盖 API 管理、运行时流量，以及是否需要单独的 agent；该 issue 未指出实现文件或测试。
