Add pagination to describeInstances in aws

For large clusters and AWS projects, the describeInstances api call
returns a 500 http error because the response exceed the limit in
the AWS api.

This means that, for example, for a classic loadbalancer, no new nodes
get added to it, which could lead to service disruption over time
due to node attrition.

This commit attempts to solve that by changing the call to use the
pagination method from the aws sdk
