When uploading an application to App Center, Jenkins outputs a message similar to this:

File found: XXX
Creating an upload resource.
Create upload resource successful.
Uploading app to resource.
Upload app to resource successful.
Committing resource.
Committing resource successful.
Distributing resource.
Distributing resource successful.

 It would be very handful to have the final URL to quickly retrieve the release in the AppCenter web interface : 

Distributing resource successful
Resource available at: https://appcenter.ms/orgs/<organisation_name>/apps/<application_name>/distribute/releases/<release_number>

Assumption:  The message Distributing resource successful is printed in the execute function of the java/io/jenkins/plugins/appcenter/task/internal/DistributeResourceTask class which seems to contain the upload URL.
