These specs assumed data was still sorted by timestamp, instead of by
ID.

Bundler keeps re-ordering this particular Gem every time something is
executed using "bundle exec".

When grabbing the projects to filter issues by we don't care about the
order they're returned in. By removing the ORDER BY the resulting query
can be quite a bit faster.

This replaces plucking of IDs with a sub-query, saving the overhead of
loading the data in Ruby and then mapping the rows to an Array of IDs.
This also scales much better when dealing with a large amount of IDs
that would be involved.

Sorting by "id" has the same effect as sorting by created_at while
performing far better and without the need of an extra index (in case
one wanted to speed up sorting by "created_at").

Sorting by "Recently updated" still uses the physical "updated_at"
column as there's no way to use the "id" column for this instead.

Certain pages (e.g. the group wide issues page) filter miletones by
their title. Without an index this will result in a sequence scan on a
large dataset increasing the total loading time of a page.

Since filtering by these values is very rare (they're mostly just
displayed as-is) we don't need to waste any index space by saving them
as tags. By storing them as values we also greatly reduce the number of
series in InfluxDB.

Add new feature to find file(recreate)

While useful for finding out what methods/views belong to a transaction
this might result in too much data being stored in InfluxDB.

This reverts commit 7549102b.

Apparently I was wrong about
ActiveSupport::Notifications::Event#duration returning the duration in
seconds, instead it returns it in milliseconds already.

Using the fuzzy filter, develop "file finder" feature.

- fuzzy filter(https://github.com/jeancroy/fuzzaldrin-plus)
- shortcuts(when "t" was hitted at tree view, go to 'file find' page and 'esc' is to go back)
- depends on gitlab_git 7.2.22

Get "Merge when build succeeds" to work when commits were pushed to MR
target branch while builds were running

The Merge when build succeeds service only merges when the MR is
mergeable (open, not WIP, no conflicts).

When the target branch is updated, all affected MRs have their merge
status set to `unchecked`, and the conflicts check will only happen
when `check_if_can_be_merged` is called, which happens when the MR page
is viewed.

When someone enables the automatic merge, the target branch is updated,
no-one views the MR page again, and the build succeeds, the mergeability
check will fail and the MR will not in fact be merged.

This MR makes sure `check_if_can_be_merged` is always called when MR
mergeability is checked.
