Add network config to all component benchmarks

[dannycjones]

This change introduces both the CRT's target network throughput configuration and the network interface configuration to each of the benchmarks for layers/components in Mountpoint's read path.

These are added primarily to support performance investigations, so we can identify where there are gaps in performance and narrow them to improve throughput of Mountpoint overall.

The target throughput default of 10.0 Gbps is removed on the lowest level of the benchmark, given we don't know what the default is for the CRT itself. It is left in place on all other layers as we default the value to 10.0 Gbps inside Mountpoint's S3 client.

Does this change impact existing behavior?

No, adds new arguments to benchmark scripts only. Even in those scripts, we alias any command line arguments that change.

Does this change need a changelog entry? Does it require a version change?

No, this is benchmarking changes only.
