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
```
