[Ethernet-IB][index] Modifed the port_util to support the VoQ Inband …

…Port (#113)

Ethernet-IB port is introduced for the VoQ chassis. This requires to define the index of the Ethernet-IB to allow the application to get the index from the port name. Follow the existing design, define the Inband port indexbase as 11000.
