add http2http plugin config

Adds support for a new "http2http" plugin in the configuration and implementation.

- Introduces a new constant `PluginHTTP2HTTP` to represent the "http2http" plugin in the plugin configuration.
- Adds `HTTP2HTTPPluginOptions` struct to define the options available for the "http2http" plugin, including local address binding, host header rewrite, and custom request headers.
- Implements the `http2http` plugin in `http2http.go`, which includes the setup of a reverse proxy server that forwards HTTP requests to another HTTP server based on the specified plugin options.
- Registers the "http2http" plugin with the plugin system, allowing it to be utilized in client configurations.
