Hello everyone!
If I subscribe to the environment monitor like `environment.monitor.subscribe(ApplicationStarted)` every time hot-reload happens it will subscribe one more function subscribed call.
is this behaviour normal?

example
```
    environment.monitor.subscribe(ApplicationStarted) {
        print("hi")
    }
```
outputs
first load
`hi15:30:45.022 [main] TRACE ktor.application - Application started: io.ktor.application.Application@1ad926d3`
second load (hot-reload)
`hihi16:24:00.587 [nioEventLoopGroup-3-1] TRACE ktor.application - Application started: io.ktor.application.Application@353d7adb`

out of curiosity, is ApplicationStopped also called?

`hihi19:59:50.527 [nioEventLoopGroup-3-1] TRACE ktor.application - Application stopped: io.ktor.application.Application@244b9b58`

`environment.monitor` is the same instance between restarts

It looks like it is working as designed then. I would expect a sane app server to restart if I reload a random class.
