Hosts using a non-standard configuration may have a different
hostname/port/scheme than what may be configured on the GitLab
server. While expose_url should generate a proper URL, there are cases
where it may not work. Since we don't need the full URL, we can use the
relative path.

When GitLab is configured with a relative URL root (e.g. /gitlab), an
error appeared, "Something went wrong while fetching related merge
requests."

This change ensures the relative URL is included.

Prevent leaking namespace and project names on moved issue links

This MR rewrites existing Related Merge Requests widget
with Vue with reusing shared Related Issues components

Before, the styling for `img:not(.emoji)`` was repeated between
`.md:not(.use-csslab):not(.wiki)` (for comments and the Markdown
preview), `.documentation.wiki` (for help pages), and
`.issuable-details .description .wiki` (for MR and issue descriptions).

In these places, we now simply use `.md`. Wherever we use `.md` but
don't want this image styling (like wikis and blobs), `.md-file` is
added.

Guest user of a project should not see branches

Style status box links using bootstrap and other utility classes instead
of styling all `a` tags in the status-box.

The text "moved" now links to the issue the closed issue was moved to.

Backports template and Vue changes from https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/9632 to CE

Add the text `(moved)` to the `Closed` status indicator on a closed
issue if the reason the issue was closed was due to moving it.

This only applies to closed issues. Issues that were closed and moved
then later re-opened only show `Open`. This makes it more immidately
clear why the issue was closed.

When a user is not logged in, we want to show the `New Issue` link so
he gets directed to the login flow first.

When a project is archived, we never want to show the link.

Instead of converting hash into JSON inside
issuable_initial_data method, return hash and convert
to JSON later. This allows us to easily extend basic
issuable data with resource specific values. For example
for Epic these data should include also labels, so we can then
do something like:
issuable_initial_data(@epic).merge(labels: @epic.labels).to_json
