Artifact Promotion Plugin - Searching new maintainer

[Halil-Cem Gürsoy]

Hi Folks,

unfortunately I've not the time to maintain this plugin and, shame on me, I haven't bothered about this for a long time. 

It would be fine if someone can take it over. 

Even in times of Docker images there is IMHO still the need for  'classic' artifacts and the handling of them.

So I'm marking this plugin for adoption, maybe someone is interested here.
