[CI] Manage the build artifacts from the configuration
This add an "artifacts" dictionary to the configuration, which maps a
glob pattern (relative to the build directory) to an artifact name
(relative to the artifact directory).
The artifact list is not guaranteed to be 100% correct, but it can't
make it worst.
Depends on D6733.
Test Plan: Run any CI build plan and look at the artifacts in Teamcity.
