[Feature Request / Question] Dynamic origins for CORS

[jellydn]

Could we have a similar option for CORS with moleculer-web as Express works with cors package?

Refer https://expressjs.com/en/resources/middleware/cors.html#configuring-cors-w-dynamic-origin

const cors = require('cors')
const app = express()

const corsOptions = {
  origin: function (origin, callback) {
    // db.loadOrigins is an example call to load
    // a list of origins from a backing database
    db.loadOrigins(function (error, origins) {
      callback(error, origins)
    })
  }
}

The problem is that, in the current implemenation the cors functions are sync and not async. I think we will able to add it in the next version only.
