Clustering: Jolokia bundle is not included in any clustering feature.

https://wiki.opendaylight.org/view/Running_and_testing_an_OpenDaylight_Cluster
suggests installing Jolokia bundle, and using it to monitor status of shards.

Waiting for shards is a useful workaround for bugs such as 2284, 2283 (and possibly more, to be discovered).

ODL should be able to run without access to external Maven repositories, but as Jolokia bundle is not dependency of any ODL clustering feature, using the workaround is difficult without Internet access.

Accidentally, Jolokia bundle (of different version) is already present in /system repository, but it is not obivous which feature can cause it to install.

Overall, I guesstimate the severity of this issue to be 'Minor'.
