Is necessary commit .slicemachine folder?

@soheima.canton well I've checked with our dev team, and in fact, you don't need to commit the whole folder, all what you need is to commit is .Slicemachine/mock-config.json and the rest is regenerated
every time you hit save in the UI.

So basically you can add the .Slicemachine to .gitignore with an exception to that file.
