Lazy diffs

Needs https://gitlab.com/gitlab-org/gitlab_git/merge_requests/65

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/10785

-   Use Gitlab::Git::DiffCollection which limits the result set size.
    This avoids loading unnecessary data from Git/SQL into memory.
-   Remove left-over Grit timeout handling code.
-   Use Gitlab::Git::Count.lines to count lines in strings.
-   Use more iterators.

Contextually teach the user about the quick submit hotkey

When a user tabs to the submit button (i.e., the "wrong" way), we
display a tooltip with the quick submit hotkey so they can learn the
"right" way.

See merge request !2802

When a user tabs to the submit button (i.e., the "wrong" way), we
display a tooltip with the quick submit hotkey so they can learn the
"right" way.

Now it will work on any field inside that form, and it's easier to scope
new behavior, which is what we're adding next!
