Stop using Mojo::IOLoop as an event emitter
|Target version:||Current Sprint|
There are quite a few uses of
Mojo::IOLoop->singleton->emit/on in openQA right now (like here https://github.com/os-autoinst/openQA/blob/700504f68dc0ebfcea51e8a180fd4d6f994f6f47/lib/OpenQA/Worker/Commands.pm#L116). But Mojo::IOLoop will be adding its own events over time and there will likely be conflicts. So it should be replaced with a new Mojo::EventEmitter based object.
