Establish a testbed for lightning storm

[hannahhoward]

What

We want to compare performance of lightning storm to vanilla bitswap and graphsync. Probably we want to utilize some kind of testground test for this.

Prior Art

There are two projects we may want to consider building within/on top of/forking/copy-pasting from:

• https://github.com/protocol/beyond-bitswap
• https://github.com/filecoin-project/data-transfer-benchmark

Key parameters

We should be able to configure our test to use different:

• latencies
• bandwidths
• shapes and sizes of DAGs (i.e. wide/deep, amount of data, etc)
• distributions of data (i.e. all peers have all, data is distributed across peers)
• possibly malicious peers?

Building a testbed is probably the first step after we do #1 before we add other features

Also wanted to flag ipfs/test-plans#4. It's currently only set up for 1:1 transfers but we could build more multi-party test plans. It's based off of the beyond bitswap work but compiles and runs with the current testground.
