Container registry publishedpath

[hennevogel]

We already do some mapping of URLs in published_path and we have configuration for container registries. We should return a registry URL in view: :publishedpath if ($repotype{'docker'}) and some registry is configured.

Seems we already do something like that in bs_publish.

What you currently get:

osc api "/build/OBS:Server:Unstable:Containers/containers/x86_64/base/openbuildservice-base.x86_64-bp154.18.167.tar?view=publishedpath"
<publishedpath project="OBS:Server:Unstable:Containers" repository="containers">
  <path>OBS:/Server:/Unstable:/Containers/containers</path>
  <url>https://download.opensuse.org/repositories/OBS:/Server:/Unstable:/Containers/containers</url>
</publishedpath>

What I would expect to get:

osc api "/build/OBS:Server:Unstable:Containers/containers/x86_64/base/openbuildservice-base.x86_64-bp154.18.167.tar?view=publishedpath"
<publishedpath project="OBS:Server:Unstable:Containers" repository="containers">
  <path>OBS:/Server:/Unstable:/Containers/containers</path>
  <url>registry.opensuse.org/obs/server/unstable/containers/containers/openbuildservice/base:latest</url>
</publishedpath>
