`MergeRequestsClosingIssues`
- Instead of overriding `create` and `update` in `MergeRequests::BaseService`
- Get all merge request service specs passing

- Don't use `TableReferences` - using `.arel_table` is shorter!
- Move some database-related code to `Gitlab::Database`
- Remove the `MergeRequest#issues_closed` and
`Issue#closed_by_merge_requests` associations. They were either
shadowing or were too similar to existing methods. They are not being
used anywhere, so it's better to remove them to reduce confusion.
- Use Rails 3-style validations
- Index for `MergeRequest::Metrics#first_deployed_to_production_at`
- Only include `CycleAnalyticsHelpers::TestGeneration` for specs that
need it.
- Other minor refactorings.

- Move more database-specific functions into `Gitlab::Database`
- Indentation changes and other minor refactorings.

2. Use cascading deletes
3. Extract an average function for the database median.
4. Move database median to `lib/gitlab/database`
5. Use `delete_all` instead of `destroy_all`
6. Minor refactoring

1. Dispatch between the two strategies automatically based on the
current database type.
2. The MySQL version needs to run multiple statements, so the
`cycle_analytics` model is modified to support this.

1. Add indexes to `CreateMergeRequestsClosingIssues` columns.
2. Remove an extraneous `check_if_open` check that is redundant now.
It would've been better to rebase this in, but that's not possible
because more people are working on this branch.

A number of failures were introduced due to performance
improvements (like pre-calculating metrics).

1. Look for merge requests (and issues that they close) that have been
deployed to production in the last X days (where X is given by the
`from` parameter).
2. Cycle analytics queries only operate on this fitered set of merge
requests and issues.

- For cycle analytics.
- Instead, make each individual `value` `null`, since the titles and
descriptions are used by the frontend even when there is no data.

1. Add `summary` section.
2. `stats` is `null` if no stats are present.
3. `stats` and `summary` are both arrays.

- Consolidate all merge request metrics into a single migration.

All the code that pre-calculates metrics for use in the cycle analytics
page.
- Ci::Pipeline -> build start/finish

- Issue -> record default metrics after save
- MergeRequest -> record default metrics after save
- Deployment -> Update "first_deployed_to_production_at" for MR metrics
- Git Push -> Update "first commit mention" for issue metrics
- Merge request create/update/refresh -> Update "merge requests closing issues"

and `value.

1. Use Arel for composable queries.
2. For a project with ~10k issues, the page loads in around 600ms.
Previously, a project with ~5k issues would have a ~20s page load
time.

- The normal seed creates all the data for cycle analytics the "right"
way. It creates issues, merge requests, commits, branches,
deployments, etc. This is good, but too slow for perf testing.
Generating a 1000 sets of records this way takes more than an hour.
- When the `CYCLE_ANALYTICS_POPULATE_METRICS_DIRECTLY` environment
variable is passed in, the seed only creates issues and merge
requests. It then adds the `metrics` for each issue and
merge request directly, to save time.
- The seed now takes about 4 minutes to run for 1000 sets of records.

1. These changes bring down page load time for 100 issues from more than
a minute to about 1.5 seconds.
2. This entire commit is composed of these types of performance
enhancements:
- Cache relevant data in `IssueMetrics` wherever possible.
- Cache relevant data in `MergeRequestMetrics` wherever possible.
- Preload metrics
3. Given these improvements, we now only need to make 4 SQL calls:
- Load all issues
- Load all merge requests
- Load all metrics for the issues
- Load all metrics for the merge requests
4. A list of all the data points that are now being pre-calculated:
a. The first time an issue is mentioned in a commit
- In `GitPushService`, find all issues mentioned by the given commit
using `ReferenceExtractor`. Set the `first_mentioned_in_commit_at`
flag for each of them.
- There seems to be a (pre-existing) bug here - files (and
therefore commits) created using the Web CI don't have
cross-references created, and issues are not closed even when
the commit title is "Fixes #xx".
b. The first time a merge request is deployed to production
When a `Deployment` is created, find all merge requests that
were merged in before the deployment, and set the
`first_deployed_to_production_at` flag for each of them.
c. The start / end time for a merge request pipeline
Hook into the `Pipeline` state machine. When the `status` moves to
`running`, find the merge requests whose tip commit matches the
pipeline, and record the `latest_build_started_at` time for each
of them. When the `status` moves to `success`, record the
`latest_build_finished_at` time.
d. The merge requests that close an issue
- This was a big cause of the performance problems we were having
with Cycle Analytics. We need to use `ReferenceExtractor` to make
this calculation, which is slow when we have to run it on a large
number of merge requests.
- When a merge request is created, updated, or refreshed, find the
issues it closes, and create an instance of
`MergeRequestsClosingIssues`, which acts as a join model between
merge requests and issues.
- If a `MergeRequestsClosingIssues` instance links a merge request
and an issue, that issue closes that merge request.
5. The `Queries` module was changed into a class, so we can cache the
results of `issues` and `merge_requests_closing_issues` across
various cycle analytics stages.
6. The code added in this commit is untested. Tests will be added in the
next commit.

- The fixture generates data for every stage in the cycle analytics
dashboard. Once this fixture has run, you shouldn't be seeing any
"<not enough data>" messages for cycle analytics.
- This is probably not necessary for every fixture run, so it might be
moved behind an env var in the future.

file) to `CycleAnalyticsHelpers`

Add a `before_end_fn` option to the code that generates cycle analytics
specs. `before_end_fn` is called before the end conditions are. Used for
data setup that needs to be called after the start conditions and before
the end conditions.

Remove overlap from the "start + end" durations in the happy test
case. For the `staging` phase, the end time is the _first_ deployment
that happens after the MR merge.
If we have 5 MRs where the `start_time`s (merge time) are the
same, and all the `end_time`s (deploy to production) a few days from
now, only the earliest deploy will get picked up, because that
consitutes a deploy for _all_ the MRs.
We fix this by removing overlap. Every `start_time` is now generated to
be _after_ the preceding `end_time`.

- Tests would randomly fail because of naming conflicts.
- Use a `random_git_name` method instead of using `FFaker` directly.

- Move the "data belongs to other project" test case into the generated
tests, and remove the explicit tests from the `code` and `plan` phases.

1. Generalise the specs that will be common across all cycle analytics
phases.
2. Rewrite specs `issue` and `plan` to use this abstracted testing
strategy.
3. Specs that are specific to a given phase, or unwieldy to test in an
abstracted manner, are added to each phase's spec.

- The `review` phase ends when a MR is merged, not "merged OR closed".
- The `code` phase starts when a MR is first mentioned in a commit, and
ends when a merge request closing the issue is created.
- The `plan` phase ends when the issue first mentioned in a commit.
---
- Fix the `median` function so it sorts the incoming data points.
- A data point where `end_time` is prior to `start_time` is invalid.
