Add a build status badge to GitLab feedback
We have two types of feedback right now:
-
Validation started with lhcb-gaudi-head#2427
for nightly builds -
Started reference and integration test builds. Once done, check the comparison of build and test results.
for ci-test builds
Both can profit from a badge integrated into the comment, which shows the progress of a build or a couple of builds. The badge image can be served by either couchdb directly or the dashboard.
