Fix name of feature that restricts access to builds traces

## What does this MR do?

This MR fixes the name of the feature that makes it possible to restrict build traces. This does not disable access to pipelines. Pipelines are still available so we should tie the name with builds, instead of using work "pipeline" there.

Delete dynamic environments

- Adds "close environment" action to a merge request
- Adds tabs to environments list
- Adds close button to each environment row in environments list
- Replaces Destroy button with Close button inside an environment
- Adds close button to builds list inside an environment

#### Configuration

In order to enable stopping environments a valid `.gitlab-ci.yml` syntax has to be used:

```
review:
  environment:
    name: review/$app
    on_stop: stop_review

stop_review:
  script: echo Delete My App
  when: manual
  environment:
    name: review/$app
    action: stop
```

This MR requires that `stop_review` has to have: `when`, `environment:name` and `environment:action` defined.
The next MR after this one will verify that and enforce that these settings are configured.

It will also implicitly configure these settings, making it possible to define it like this:

```
review:
  environment:
    name: review/$app
    on_stop: stop_review

stop_review:
  script: echo Delete My App
```

Wait for ajax for every merge request spinach test

## What does this MR do?

* removes duplicate `WaitForAjax` module
* ensure we run `wait_for_ajax`after each MR spinach tests

## Why was this MR needed?

Because when visit MR page we do ajax call to check CI status. When testing this page with spinach and JS driver we got random failing tests. It happens because of race condition db cleaner drop data before ajax call finished. So we make sure that every MR spinach scenario with js driver waits for ajax before running next scenario
