Machine API related house keeping

[gazarenkov]

It is umbrella epic to cover cleaning all the machine API related things.

The problem is that as a result of evolution of our vision many abstractions, classes, UI components and even API(s) now looks odd.
It is a quite big pile of code which we do not effectively use but have to support, test and package.
But the even bigger problem is that such a code makes a big deal of confusing for community developers who is not familiar with the history.

Could you clarify on what "remove machine API since it is not used anymore" means?

Based on an earlier comment at #2847 (comment)
it seems that the Machine API can be used to create machines that are not just docker-based. Are you removing this feature and making an assumption that all machines in the future will be docker-based?

no no - definitely keeping the ability to swap out docker runtimes for other runtimes. We depend upon that in a number of ways. I think it was just a language thing in his explanation of how the API will be refactored.

Thanks for the clarification @TylerJewell.

BTW - the 5.0.0 release has been made, though we have a lot of cleanup stuff around docs and other areas before we ship it. So you are seeing a lot of housekeeping issues being created as we are taking the next couple months to focus on performance, code cleanup, and other things to make the project easier to manage.
