Originally, we used to use a build step to notify Phorge of the status of builds. There is one problem with it: When there is no available worker, Phorge does not know the build link. This commit changes it to use a dedicated reporter, so the link can be displayed even if there is no available worker.

Type: add

Run a build and verify you can see the artifact link immediately, and you can see the status when the build ends.
