Support defining the top commit up to which to update. In other words, this makes it possible to update up to certain point other than the branch head. The update point (git commitish) is given on the command line by appending the component name(s) with a colon and the commitish, e.g. $ combo-layer update my_component:sha1 Only the "update" action supports this.
