Provide different branch ordering

[durzo]

Our project needs certain branches merged before others, is there any way to tell octopus to merge branch FEATURE/Y first, then FEATURE/Z ?

The only ordering is alphabetical. Even If you change the argument order, it won't change the result. The computation is here https://github.com/lesfurets/git-octopus/blob/master/src/git-octopus#L100
