Change openjdk baseOS img to integration-java11

Change openjdk baseOS img to integration-java11

This change should not have any effects on functionality as integration
image is built on top of adoptopenjdk/openjdk11:jre-11.0.8_10-alpine.

Benefits from switching over:
* minimal {java11,python} images maintained by integration team
* using currently "blessed by seccom" versions (:latest tag used)
* should limit spread of legal issues across layers
* integration images will be the first to have automated compliance
  documentation
* should limit spread of base layers (contributing to deployment
  footprint - more base layers = more to download, more to store etc...)
