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.

Clean up the `issue` tests as well

- 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.

All users with "Reporter" access (and above) to a project can see the
Cycle Analytics page.

1. Supported date ranges are 30 / 90 days ago. The default is 90 days
   ago.

2. All issues created before "x days ago" are filtered out, even if they
   have other related data (test runs, merge requests) within the filter
   range.

- <Not enough data> wasn't being displayed in the 'Issue' and 'Plan'
  sections.

1. Pass in an array of queries - the first to return a value will be
   used. This makes it easier to add more heuristics later.

2. Convert all queries with 'or' in the title to two separate queries.

3. Rename all `mr_` methods to `merge_request_`

1. Rewrite the `Queries` module to work off a `data_point` hash, with
   `issue` and `merge_request` as keys. The "production" query needs
   both an issue and a merge request to make it's calculation, so it
   makes sense to keep things consistent and provide the same
   data (issue + merge request) for all queries.

1. Record the `wip_flag_first_removed_at` and
   `first_assigned_to_user_other_than_author` metrics for a merge
   request. Use a `merge_request_metrics` table, similar to the one for
   `issues`. Metrics are recorded `after_save`.

2. Move larger queries to a `CycleAnalytics::Queries` module.

1. Move from raw SQL to ActiveRecord.
2. Add a non-persisted `CycleAnalytics` model to store all the queries.

1. Code is messy and untested, but it is a start.

- And store the `first_associated_with_milestone_at` and
  `first_added_to_board_at` times, when an issue is saved.

Capitalize mentioned issue timeline notes

## What does this MR do?
Renames `mentioned in` to `Mentioned in` for issue timeline notes

## Are there points in the code the reviewer needs to double check?
Shouldn't be any 😄 

## Why was this MR needed?
Resolves existing UI inconsistency as all the other issue timeline notes have their first letter capitalized.

Fix external issue tracker "Issues" link leading to 404s

## What does this MR do?

This MR fixes the redirection to the wrong URL when using an external issue tracker, such as JIRA or Redmine.  a70431f8 modified the behavior to link to the external issue tracker
issues URL instead of the project path URL. This restores the previous behavior.

## Why was this MR needed?

The issues URL often has `:id` associated with it for linking mentioned issues.
For external issue trackers, the project page is the intended target.

## What are the relevant issue numbers?

Closes #21252

Related to #21402

Remove max height on pipelines graph

#### What does this MR do?
Removes max-height from pipeline graph

#### Why was this MR needed?
The height was originally put in place because some stages have ~20 tests, which ends up looking a little lopsided and there's a large amount of white space. The scrolling container, however, is not the best solution and ends up being more difficult to scroll around to find what you're looking for. For now we can remove the height, and eventually we'll have the similar tests collapsed.
