[MR Analytics] Allow not filters on labels and milestones
How labels filtering on code review currently looks like?
How labels filtering on MR analytics currently looks like?
Problem statement
Similar to how it is on the issues list, MR list, code review pages, it makes a lot of sense to use not
filter on some fields (specifically, labels, assignees, reviewers, milestones and iterations). Some fields don't yet have an backend implementation for not filtering and are being discussed here: #219201 (comment 432478991), but labels, milestones, author and assignees do support not filters and are used extensively elsewhere and should be provided on all filtering interfaces.
