// Registers the specified targets with the specified target group.
//
// If the target is an EC2 instance, it must be in the running state when you
// register it.
//
// By default, the load balancer routes requests to registered targets using the
// protocol and port for the target group. Alternatively, you can override the port
// for a target when you register it. You can register each EC2 instance or IP
// address with the same target group multiple times using different ports.
//
// With a Network Load Balancer, you cannot register instances by instance ID if
// they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1,
// G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by
// IP address.
