Apisix Upstream And Load Balancing Configuration

** - APISIX Model Context Protocol (MCP) server is used to bridge large language models (LLMs) with the APISIX Admin API, supporting querying and managing all resources in [Apache APISIX](https://github.com/apache/apisix).

Unique: Exposes APISIX upstream and load balancing configuration as MCP tools with validation of health check parameters and load balancing algorithm selection. Enables LLMs to manage complex backend topologies through structured tool calls.

vs others: Provides LLM-native upstream and load balancing management unlike manual configuration, enabling dynamic backend topology changes through conversational commands
