Validate whether the local branch is synced with the origin?

[sorin-costea]

When I trigger a deploy from my machine, I might forget sometimes to pull. Thus I package happily from what I thought to be HEAD. I also tried to fetch, but even when I see that FETCH_HEAD is different than HEAD, the build still succeeds.

Could I have some kind of validation which would fail if the checked out branch is not synced with its origin? I'd like to see it failing the build the same why like the validation for uncommited changes.

I'm aware this wouldn't be an issue if the CI would work but well..
