Plugin-Blocklist
A blocklist can be maintained under resources/init.groovy.d/plugin-blocklist.json. This can also be maintained via the etcd-key 'config/jenkins/blocked.plugins'. A comma-separated list must be passed to the key, e.g:
etcdctl set config/jenkins/blocked.plugins pluginId1,pluginId2,pluginId3,pluginId4
Plugins that are entered in this blocklist are removed when the Jenkins Dogu is restarted.
