FlavourTagging Development for master
This MR applies the latest FlavourTagging-related changes that have already been cherry-picked for 2018-patches, including (the very large) !319 (merged), !327 (merged), and !338 (merged).
This should be the last part of the merge campaign we discussed @erodrigu. Ping @sakar @mschille.
@vibattis we may need to keep this MR in mind and cherry-pick !346 (merged) ourselves as soon as it was merged.
This MR needs to be combined with Analysis!359 (merged) and Stripping!807 (merged)
