Minor fixes on env vars and runtime for kubernetes (#1389)

* fix: Fix env vars on k8s

The vars used by quarkus need to be upper case
and dots replaced by underscore to work

* fix(app): Fix unused JAVA_OPTS from kavaran-app docker image

Now the ENV will be used on the command line
(that was replaced from exec form to shell form of docker's CMD
as in the the devmode docker image)

* fix(app): Adds default runtime for jbang build on kubernetes

Without this the build fails.
(was added too the possibility to configure other runtime with an env var)

* chore(app): Removed defaults of JAVA_OPTS from kavaran-app docker image

Not needed anymore since Hazelcast was replaced by plain maps

* fix(app): Adds default runtime for jbang build on docker

* chore(app): Removed Hazelcast java opts from docker image

Not needed anymore since Hazelcast was replaced by plain maps
