    Assigns one or more secondary private IP addresses to a network interface.

    network_interface_id
        (string) - ID of the network interface to associate the IP with (exclusive with 'network_interface_name')
    network_interface_name
        (string) - Name of the network interface to associate the IP with (exclusive with 'network_interface_id')
    private_ip_addresses
        (list) - Assigns the specified IP addresses as secondary IP addresses to the network interface (exclusive with 'secondary_private_ip_address_count')
    secondary_private_ip_address_count
        (int) - The number of secondary IP addresses to assign to the network interface. (exclusive with 'private_ip_addresses')
    allow_reassociation
        (bool)   – Allow a currently associated EIP to be re-associated with the new instance or interface.

    returns
        (bool)   - True on success, False on failure.
