Included the following internal dependencies explicitly in the pom.xml to fix the security vulnerability issues

• jackson-databind (Internally used in pubnub-gson, updating this version didn't help)
• snake yaml and okio (These are internal dependencies in the kubernetes-client, updating this did not help)
• Also fixed the below:
