Including wasm runtime into "result" service

[RomanShushakov]

Hello everyone,

I played around a bit with including wasm_runtime support in the current example, I forked from the current repository and used wasm runtime for the "result" service. You can view the code in example-voting-app_wasm-runtime. If you have time and thoughts about adding the Wasm runtime to the current repository, I would be happy to help you with this task.
Sorry if proposal inappropriate.

Thank you
Roman
