Fix plugin dependencies

Jenkins was unable to load some plugins, since a dependency was updated
and not compatible anymore with the fixed versions configured in this
project.

This change fixes the plugin configuration by
- updating workflow-step-api to 2.18
- fixing display-url-api to last compatible version 2.3.0
- fixing blueocean-display-url to 2.2.0
- fixing docker-commons to 1.13
- fixing docker-workflow to 1.17
- fixing and updating credentials-binding to 1.18
