**Description**

The ib-loopback test was regressed due to this recent
[change](https://github.com/microsoft/superbenchmark/commit/c65ae56713d6bfcc4a3be37d7fe24779590f9791).
When running ib-loopback using the standard
[config](https://github.com/microsoft/superbenchmark/blob/c65ae56713d6bfcc4a3be37d7fe24779590f9791/superbench/config/default.yaml#L69

),
the test would fail since it would pass numeric values like `0` into the
test command which would break since it is not a valid IB device name.

Example failure:

Benchmarks: micro benchmarks - add --set_ib_devices option to auto-select IB device by MPI local rank in ib validation (#733)

**Description**
add --set_ib_devices option to auto-select IB device by MPI local rank 


**Major Revision**
- Add a new CLI flag --set_ib_devices to automatically select irregular
IB devices based on the MPI local rank.
- When enabled, the benchmark queries available IB devices via
network.get_ib_devices() and selects the device corresponding to
OMPI_COMM_WORLD_LOCAL_RANK.
- Fall back to existing --ib_dev behavior when the flag is not provided.

**Minor Revision**
- Add an env in network.get_ib_devices() to allow user to set the device
name

**Description**
Fix code insecure issue that binds a socket to all network interfaces.

Update network common utils. Add get_ib_devices in network common utils and move get_free_port from test utils to network common utils
