When one tries to define the management http listener as, for example,
`172.25.0.2:8081`, ranch is given `{port, {"172.25.0.2",8081}}` and
breaks.
```sh
env EMQX_MANAGEMENT__LISTENER__HTTP=172.25.0.2:8081 make quickrun
```
```

So, it’s currently not possible to make the management listener bind
to a specific interface.
One step closer for better code abstraction for opensorce vs enterprise
So far this relocation is to make opensource to enterprise merges
conflict free.
