Add new copy votes policy for merge commits
Adds new 'copyAllScoresOnMergeFirstParentUpdate' vote policy. This
policy allows to carry over votes on "merge commit rebase". This meas
when only first (left parent) changes and rest of parent(s) stays the
same.
Such policy is useful for changes that are merge commit of feature
branches that tracks destination branch. When it is enabled it reduces
the overhead of CI and human reviews on merge commits that only
incorporate newer changes from destination branch in next patch set.

+This policy is useful if you don't want to trigger CI or human
+verification again if your target branch moved on but the feature
+branch being merged into the target branch did not change. It only
+applies if the patch set is a merge commit.
+
+If true, all scores for the label are copied forward when a new
+patch set is uploaded that is a new merge commit which only
+differs from the previous patch set in its first parent. The
+first parent would be the parent of the merge commit that is part
+of the change's target branch, whereas the other parent(s) refer to
+the feature branch(es) to be merged.
+Defaults to false.
