how to read file in wasm

[bianpengyuan]

Host does not yet support file read ABI: proxy-wasm/proxy-wasm-cpp-host#127

The read-only file access is being actively worked on... But why exactly do you need it?

Note that the recommended way to configure plugins is to add the configuration in the proxy config itself, which is then available in the plugin via proxy_get_buffer_bytes(WasmBufferType::PluginConfiguration, ...).

This kind of requirement is more common, for example, we use wasm to do some traffic processing work, which will involve policy reading, so we need to read the mounted configuration from the envoy proxy

@PiotrSikora In addition，If the policy is complex and confidential, it is obviously not wise to put it all in the proxy configuration
