Read track from deployment and visualise canary deployments
What does this MR do?
This adds a proposal described here: https://gitlab.com/gitlab-org/gitlab-ee/issues/1659#note_25879072. Basically support for label track:.
By default if there's no track: we assume that it is stable. If there's we select whether this is canary or stable. And this data is returned in status.json for Deployboard:
{
"instances": [
{
"status": "finished",
"tooltip": "production (pod 0) Finished",
"track": "stable",
"stable": true
},This is based on https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/10379
