Add new fileinfinbiand xml definition

[sihara]

I would add another infiniband (e.g. infiniband2) definition file with perfquery rather than scan /sys/class/infiniband/xxxx/ports/x/counters, but would aslo keep current infinbiand xml file for compatibility.
The reason of why it needs new infiniband xml files because systems don't have /sys/class/infiniband/xxxx/ports/x/counters (e.g. docker environment) that is not able to collect infiniband metrics by filedata.

Here is example how to capture IB stats with perfquery.

LID can be found from /sys/class/infiniband/mlx5_$i/ports/1/lid

[root@amd01 ~]# for i in `seq 0 5`; do cat /sys/class/infiniband/mlx5_$i/ports/1/lid; done
0x58
0x0
0xffff
0x0
0x5a
0x0

perfquery requires LID and port number. "0xffff" means presented and 0x0 means not Infiniband mode.

[root@amd01 ~]# for i in `seq 0 5`; do                                                    
> perf
perf       perfquery  
> perfquery $(cat /sys/class/infiniband/mlx5_$i/ports/1/lid) 1
> done
