// Creates a Traffic Mirror session. A Traffic Mirror session actively copies
// packets from a Traffic Mirror source to a Traffic Mirror target. Create a
// filter, and then assign it to the session to define a subset of the traffic to
// mirror, for example all TCP traffic. The Traffic Mirror source and the Traffic
// Mirror target (monitoring appliances) can be in the same VPC, or in a different
// VPC connected via VPC peering or a transit gateway. By default, no traffic is
// mirrored. Use CreateTrafficMirrorFilter
// (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateTrafficMirrorFilter.htm)
// to create filter rules that specify the traffic to mirror.
