### Description of PR
This PR aims bigtop users can use Java 11 when they package some projects on
a docker container.
- The behavior of bigtop is not changed.
- If user set an option, bigtop pass a flag to the docker container by
environment variable. If build target project can receive the flag, bigtop
switch `JAVA_HOME` to change the Java version.
### How was this patch tested?
#### Installation of JDK 11
I checked below on aarch 64 machine
```sh
# build bigtop/slave
cd docker/bigtop-slaves/
OS_LIST=( ubuntu-18.04 ubuntu-20.04 ubuntu-22.04 debian-10 debian-11
centos-7 rockylinux-8 fedora-35 fedora-36 )
for OS in ${OS_LIST[@]} ; do
./build.sh trunk-${OS}
done
# check the installation
for OS in ${OS_LIST[@]} ; do
echo $OS;
docker run -i --rm bigtop/slaves:trunk-$OS-aarch64 ls /usr/lib/jvm;
echo ""
done
```
The default JAVA_HOME is set to 8 by `/etc/profile.d/bigtop.sh` so
installation does not affect on it.
#### Build Kafka 2.8.1 by Java 11
I checked below on aarch 64 machine.
```sh
./gradlew zookeeper-pkg-ind kafka-pkg-ind -Ppreferred-java-version=11
-POS=rockylinux-8
```
I checked Java version by inserting `mvn --version` or `gradle --version` to
`do-component-build`.
Zookeeper was build by 8 and Kafka was by 11.
