add elb account lookup @​mcalhoun (#​11)

#### what - Update the `outputs` to make `elb_logging_account` its own output #### why - In [#​10](https://togithub.com/cloudposse/terraform-aws-utils/issues/10) I mistakenly added this output to the `region_az_alt_code_maps` output

add elb account lookup @​mcalhoun (#​10)

##### what - Add a lookup for ELB accounts for Elastic Load Balancer accounts ##### why - When creating bucket policies to allow logging from ELB/ALB to write their access logs to S3, it is necessary to give permissions to the dedicated account the ELB/ALB is created in. ##### references - [AWS Documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-access-logs.html#access-logging-bucket-permissions)
