Deploy messages should be canary-aware
Description
When using canary deploys, we show a message on associated merge requests as if a full deploy was done.
The message should somehow acknowledge that it was only a canary deploy, thus only a portion of production is running this MR.

Documentation blurb
(Write the start of the documentation of this feature here, include:
- Why should someone use it; what's the underlying problem.
- What is the solution.
- How does someone use this
During implementation, this can then be copied and used as a starter for the documentation.)
