Bump Jolokia version used in images to 2.1.0

[manusa]

Description

Jolokia 2.1.0 was released: https://jolokia.org/#jolokia_2_1_0_released

We need to update the Jolokia dependency used in our container images (https://github.com/eclipse-jkube/jkube-images/) to use the latest version.

Tasks

• Create a new version for the org.eclipse.jkube.jolokia module.
• Update the module dependency on the affected images
