## Are there points in the code the reviewer needs to double check?

In order to get multiple alerts to appear manually while testing, I simply added the following block to [app/views/shared/_no_password.html.haml](app/views/shared/_no_password.html.haml):

```

.no-password-message.alert.alert-warning.hidden-xs
  You won't be able to pull or push project code via #{gitlab_config.protocol.upcase} until you #{link_to 'set a password', edit_profile_password_path} on your account

  .pull-right
    = link_to "Don't show again", profile_path(user: {hide_no_password: true}), method: :put
    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'

.no-password-message.alert.alert-warning.hidden-xs

  .pull-right
    = link_to "Don't show again", profile_path(user: {hide_no_password: true}), method: :put
    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'

  You won't be able to pull or push project code via #{gitlab_config.protocol.upcase} until you #{link_to 'set a password', edit_profile_password_path} on your account

  .pull-right

    |
    = link_to 'Remind later', '#', class: 'hide-no-password-message'
```


## Why was this MR needed?

More alert-warning stripes are coming via the CI usage limits implementation in EE (https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/965), and these layout margins and colors were becoming messy.

Make autocomplete request performant

## What does this MR do?

Restricts the `autocomplete_sources`action to returning the `json`of one specific `at` type at a time.

Makes sure all commands start by immediately showing the `loading` dropdown.

If the `loading` dropdown is active, we will request and load in the data for that specific `at` type. We manually trigger the filter again. This time, if `loading` dropdown is not active, initiate default filter behaviour and use the correct data template.

Also fixes an issue where `setup` was called multiple times by only setting up and destroying atwho on a focused/blured input.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

`autocomplete_sources` was requested on page load and is large.

## Screenshots (if relevant)

3 requests for 3 different first-time references.

Resolve "Manual actions on pipeline graph"

## What does this MR do?
Improves the pipeline graph:
- add actions to each node
- always show the status icon
- improves style
- adds new icons to use only on the pipeline graph
- fixes tooltip body
- adds partial to render the graph node

### Hover state:
@dimitrieh 

This MR does not implements 100% of the mockups - https://gitlab-org.gitlab.io/gitlab-design/progress/dimitrie/pipelines-graphic/22604-spec-previews/#artboard0

As you can see in the mockups, each node has 2 separate hover states, one for the all content and one for the action icon.
In order to not hover the all content when we hover the action icon we would need to refactor the all HTML & CSS of all the pipeline graph, lines included.
The hover problem can be seen in the following video.
[video](https://drive.google.com/file/d/0B2xW80W4hUf0cnJoS1RGQ2hWZlU/view)

As you can see in the video, the build node is hovered even when the mouse seems to be far from the element.

It does not seem wise to me to change the HTML & CSS now for two reasons:
- we would need to rewrite almost everything;
- we will probably rewrite everything when we move this to vue.

Given the latter point, and considering it will be a bug effort to make the hover states equal to the mockups, I suggest we do that when we rewrite the all view.
This is fixable, though, but requires some effort & time.

I can, although, be missing something. @annabeldunstone do you see any quick/easy fix here?
