Create conditional "Enable Review App" button

Problem to solve

As part of &2349 we want to make configuring review apps easier for the user.

Intended users

• Sasha (Software Developer)
• Devon (DevOps Engineer)

Further details

Proposal

A button named "Enable review app" should be created. It should be located on the environment page.

Conditions for this button to appear:

• No review app exists.
• Project does not use AutoDevOps
• The project is "reviewable". I created a Rails sample project and a Pages project. With AutoDevOps turned on and a Kubernetes cluster linked to each project, there's no review stage for the Pages one, while there is one for the Rails project.

Pressing the button should open a modal that tells the user to copy this snippet to the gitlab-ci.yml file

deploy_review:

stage: deploy

script:

  - echo "Deploy a review app"

environment:

  name: review/$CI_COMMIT_REF_NAME

  url: http://$CI_ENVIRONMENT_SLUG.$KUBE_INGRESS_BASE_DOMAIN

only:

  - branches

except:

  - master

Together with instructions to the user

UX Proposal

If the above conditions are met display an Enable Review App button on the environments page.

On clicking the button, open a modal as shown

Links shown in the steps:

• Step 1 - 'configured' should link to the cluster page (-/clusters) https://docs.gitlab.com/ee/user/project/clusters/add_remove_clusters.html
• Step 3 - 'gitlab-ci.yml' should link to the project yaml file (blob/master/.gitlab-ci.yml)

Note: A similar look and feel for modal can be seen by clicking the Review button in MRs that do not have visual review enabled.
