#6114 Using UBI base image for Kafka Streams quickstart

[gunnarmorling]

RocksDB (a dependency of Kafka Streams) isn't compatible with Alpine.
Hence Kafka Streams cannot be used with the default Dockerfile.jvm as
generated by Quarkus atm.
The quickstart guide will be updated accordingly and this example is
updated to verify things work with UBI + installed JDK.

Check list:

Your pull request:

• targets the development branch
• uses the 999-SNAPSHOT version of Quarkus

• works in native (mvn clean package -Pnative)
• has native tests (mvn clean verify -Pnative)
• makes sure the documentation must not be updated

• updates or creates the README.md file (with build and run instructions)
• For new quickstart, is located in the directory component-quickstart
• For new quickstart, is added to the root pom.xml and README.md

Docs PR will follow up in a bit.

Hey @cescoffier, do we still need this one? I remember you were about to do some similar change on a more broad level anyways?

[cescoffier]

No, but we would need to update all the Dockerfile we have here with the new UBI-based one.

This one is not needed anymore, @cescoffier fixed it globally.
