Changed Cisco NXOS show interface transceiver command parser to fix error with vendor ID

[SaschaSchwarzK]

The parsing of a Nexus3500 C3548P-10GX version 7.0(3)I7(7) failed with the error below:

Ethernet1/2
    transceiver is present
    type is SFP-H10GB-CU1M
    name is CISCO-MOLEX
    part number is 74752-9519
    revision is 09
    serial number is MOCxxxxxxxxB
    nominal bitrate is 10300 MBit/sec
    Link length supported for copper is 1 m
    cisco id is 3
    cisco extended id number is 4
    cisco part number is 37-0960-03
    cisco product id is SFP-H10GB-CU1M
    cisco vendor id is V03   -> Error



    raise TextFSMError('State Error raised. Rule Line: %s. Input Line: %s'
textfsm.parser.TextFSMError: State Error raised. Rule Line: 25. Input Line:     cisco vendor id is V03

This change will fix this issue, but also add two new fields "status" and "product_id".

The "status" field can not only be used to determine if a transceiver is present or not, but also if the port does support transceivers or not("not applicable"). This can help to identify fixed copper ports on Fabric extenders or 1/10GBaseT ports on Nexus 9k. This change will produce more results as no item was generated when an SFP was not present, but that could easily be sorted out by matching on the value for the status.

The "product_id" field is helpful to get a Cisco like Part ID for a non Cisco transceiver like in the examples below.
