EKS issues in files apply and 04-allow-cluster-to-access-rds.sh

[nsutphen1]

In the file apply, the method apply_template is called on worker-service.yml and web-service.yml. These files don't exist in the project.

In the file 04-allow-cluster-to-access-rds.sh in the code
kubectl run \ -i \ --restart=Never \ --rm \ --env PGPASSWORD="$POSTGRES_PASSWORD" \
The environment variable PGPASSWORD does not exist, it should be POSTGRES_PASSWORD.
