# Create a new Elastic Load Balancer
#
# ==== Parameters
# * availability_zones<~Array> - List of availability zones for the ELB
# * lb_name<~String> - Name for the new ELB -- must be unique
# * listeners<~Array> - Array of Hashes describing ELB listeners to assign to the ELB
# * 'Protocol'<~String> - Protocol to use. Either HTTP, HTTPS, TCP or SSL.
# * 'LoadBalancerPort'<~Integer> - The port that the ELB will listen to for outside traffic
# * 'InstancePort'<~Integer> - The port on the instance that the ELB will forward traffic to
# * 'InstanceProtocol'<~String> - Protocol for sending traffic to an instance. Either HTTP, HTTPS, TCP or SSL.
# * 'SSLCertificateId'<~String> - ARN of the server certificate
# ==== Returns
# * response<~Excon::Response>:
# * body<~Hash>:
# * 'ResponseMetadata'<~Hash>:
# * 'RequestId'<~String> - Id of request
# * 'CreateLoadBalancerResult'<~Hash>:
# * 'DNSName'<~String> - DNS name for the newly created ELB
