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

LDAP login style fixups

## What does this MR do?
* Addresses regression found here: https://gitlab.com/gitlab-org/gitlab-ce/issues/23435
* Adds border radius to left/right tabs

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

So you know what you're seeing, there are three types of fixes going on here: 

1. Template syntax errors that were displaying template-like language in the DOM (specifically with ldap and crowd username labels
2. Aesthetic problems in tabs that arise with more than 2 tabs
3. LDAP and crowd tab functionality. I had to move each panel into its own login box, to ensure that each panel's id synced with its associated tab's href, and that each panel was at an equal depth within the DOM. I assumed bootstrap tabs would look deeper into the login-box to find panels that matched the tabs. This is not true. The reason I didn't catch this is that in development I was just manually changing template flags to force rendering. I didn't realize I could enable ldap in CE within the gitlab.yml file 🤦
