SAMZA-2449: Create an example job in samza-hello-samza for job coordinator split deployment

[cameronlee314]

Feature: Adding an example for how to set up job coordinator dependency isolation in samza-hello-samza

Changes:

1. Updated build.gradle to include tasks to build framework artifacts.
2. Added a new config for a job to be deployed in a job coordinator dependency isolation mode.

Usage instructions:

1. Normally, the samza-hello-samza artifact would be built by running ./gradlew distTar. For dependency isolation, run ./gradlew distTar frameworkApiDistTar frameworkInfrastructureDistTar, which will build the framework API and infrastructure packages.
2. The wikipedia-application-with-framework.properties config is set up to run in dependency isolation mode. Use that as the argument to the --config-path option when running with run-app.sh.
