Hi! Thanks for the pull request 👍 In that case, do you think it would make sense to wait for the completion of Reference: https://nodejs.org/api/http.html#serverclosecallback |

That is already what is done. The only way to wait for it, is to pass the callback function, which the current code already does. It is not an awaitable function, since it does not return a Promise. |

Before this change, `await io.close();` would resolve before the HTTP server was properly shut down. Related: #4971

The kind of change this PR does introduce
Current behavior
The close of the server does not await the async close operations of the adapters like the MongoAdapter, leading to errors due to premature closing of the underlying connection.
New behavior
The close awaits the async operations on the adapters of the different namespaces. This allows to be sure that e.g. the Mongo connection can be safely disposed of.
Other information (e.g. related issues)
I've chose the
Promise.allSettledto avoid being too disruptive, since the current synchronous implementation already disregards any errors the closing of the adapters might raise.
