2.2 release branch created

Hi *, I've just created the branch for the 2.2 Cabal/cabal-install release [1]. If everything goes according to plan, the final release will be out approximately in two weeks' time, i.e. around the end of the month. This is a delay of one month compared with the original plan shared in the previous status update [2]. Hopefully, this time there won't be any more additional delays. Cheers, Mikhail [1] https://github.com/haskell/cabal/tree/2.2 [2] https://mail.haskell.org/pipermail/cabal-devel/2017-December/010410.html
