We should be able to show to the user the commits that they are ahead or behind of the remote tracking branch. The git command for this purpose is:

Git OUT

 git log --pretty=format:'%C(yellow)%h%Creset: %Cblue%an%Creset %s' --abbrev-commit --graph @\{u}..

Git IN

git fetch && git log --pretty=format:'%C(yellow)%h%Creset: %Cblue%an%Creset %s' --abbrev-commit --graph ..@{u}

Of course, we should use gitpython for this purpose and use `iter_commits` when the repo is ahead or behind. This should also have a frontend ticket where the output is shown to user.
