Kubernetes membership scheme bundle is not compatible with Java 8 runtimes

[sadilchamishka]

Description:
The Kubernetes membership scheme bundle is compatible for Java 9 or higher runtimes. The maven bundle plugin has generated that configuration and has to change it to make compatible for Java 8 or higher runtimes.

Steps to reproduce:

1 - Install Java 8 and select any carbon product (WSO2-IS)

2 - Download kubernetes-membership-scheme-1.0.8.jar and dnsjava-2.1.8.jar

https://maven.wso2.org/nexus/content/repositories/releases/org/wso2/carbon/kubernetes/artifacts/kubernetes-membership-scheme/1.0.8/kubernetes-membership-scheme-1.0.8.jar

https://repo1.maven.org/maven2/dnsjava/dnsjava/2.1.8/dnsjava-2.1.8.jar

3 - Put the kubernetes-membership-scheme-1.0.8.jar inside ./repository/components/dropins. Put the dnsjava-2.1.8.jar inside the ./repository/components/lib folder.

4 - Start the carbon product with OSGI console enabled. Check the status of kubernetes-membership-scheme bundle.

The kubernetes-membership-scheme-1.0.8 bundle would not be resolved and show the following error.

The reasoning for the issue is the maven bundle plugin impose restriction to allow Java 9 or more runtimes as shown below as per the MANIFEST.MF of that bundle.
