OpenShift - Java command and arguments mapping

When deploying a Quarkus application into OpenShift, by default the container configuration to run the application looked like:

command: java
args:
    - '-Dquarkus.http.host=0.0.0.0'
    - '-Djava.util.logging.manager=org.jboss.logmanager.LogManager'
    - '-jar'
    - /deployments/quarkus-run.jar

Both command and args fields can be overriden via the quarkus.openshift.command and quarkus.openshift.arguments properties.

However, users can't simple append their custom Java arguments, for example: java -jar /deployments/quarkus-run.jar param1 param2. The only workaround was to copy and paste the existing content in the default args field and append the custom arguments param1 and param2.

This has been fixed in 2.0 by moving all the Java related parameters into the command field:

command: 
    - 'java'
    - '-Dquarkus.http.host=0.0.0.0'
    - '-Djava.util.logging.manager=org.jboss.logmanager.LogManager'
    - '-jar'
    - /deployments/quarkus-run.jar

Now, users can use the quarkus.openshift.arguments property to append their custom Java arguments, for example: quarkus.openshift.arguments=param1,param2.
