hyp list cluster-stack ignores boto3 pagination

[nicolasj92]

hyp list cluster-stack utilizes boto3's list_stacks. This function introduces a pagination mechanism when the output gets too long (https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/cloudformation/client/list_stacks.html). This needs to be handled in the CLI code, otherwise not all stacks will be visible when running hyp list cluster-stack if there are many CloudFormation stacks in the account and region.
