Enable Deployments

Looks like we could support Deployments now.

Would need to combine;

• https://docs.gitlab.com/ee/user/project/integrations/webhooks.html#pipeline-events
• https://docs.gitlab.com/ee/api/deployments.html#list-of-merge-requests-associated-with-a-deployment
• https://docs.gitlab.com/ee/api/pipelines.html#get-a-single-pipeline
• https://docs.gitlab.com/ee/api/jobs.html#get-a-single-job
• https://docs.gitlab.com/ee/api/environments.html#create-a-new-environment

In more of an official state so this would be really good...
