Feature request: WebAssembly for Docker WasmEdge

[OSA413]

As suggested in issue #340, I'm opening a new request.

In the past years WASM started to gain popularity and now it is possible to easily build a WASM executable from Rust.

The following article provides instructions and a simple repository for building a WASM image for Docker to run https://wasmedge.org/docs/start/build-and-run/docker_wasm/

There're also a few articles that provide examples of http-server in Docker WASM

• https://blog.logrocket.com/rust-microservices-server-side-webassembly/
• https://blog.kubesimplify.com/embed-http-servers-in-wasm-with-rust-and-csharp

Motivation: WASM image size is much lighter than the same rust program with minimal Linux image (as mentioned in the WasmEdge article).

Would that be possible to build an actix-web application into WASM and what obstacles are currently present in achieving it?
