Adding support for metrics alerts disabled multiple query support.
To avoid a data model refactor, this enables the visual of multiple
queries per chart on the front end, combining queries based on
metric group, title, and y-axis label.

This also adds support for adding and editing alerts based on the
query selected rather than the single metric associated with the chart.

Resolve "Improve diff nav header"

See merge request gitlab-org/gitlab-ce!26557

Remove duplicates returned by Issues#related_merge_requests API that
relies on ReferencedMergeRequestsService which returns 2 arrays one of
related MRs and one of related MRs that close the issue(i.e. a subset
of first one). We only need related MRs in this case so just pick the
first array.

Projects that included reserved words (e.g. test-create) would fail to
generate a proper ETag key because of the name. To fix this, we add
forward slashes to match the exact name so that /test-create doesn't get
matched, but /create does.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/60113

- Compare versions header is full width except in the unified diff mode
with no tree sidebar
  - Bar is always full width, but the content within stays centered when
unified and no tree sidebar
- File header is the same height as the "Compare versions header"
- aligns with the design system grid guidelines => 56px
- Diff file headers use a button group, switch icon order to open file
externally being the last option, all buttons will become icon buttons
(icon delivery by @dimitrieh)
- If a file header becomes sticky no rounded corner/double border
problem is visible anymore
