Add build/publish jobs for binaries (mender-cli and mender-artifact)
Add build/publish jobs for binaries (mender-cli and mender-artifact)

These are build also in build_servers and used for tests. However, the
build instructions are different there (i.e. no multiplatform).

Instead of complicating even more the build script, we create new jobs
that replicate mender-cli and mender-artifact Pipelines build/publish.

Changelog: None
