testground/tests: implement TC-002

[Bidon15]

We already have all the presets done in node_sync.go
The only left to do is:

• Create more composition files reflecting data
• Adjust the bandwidths
• Better documentation tracing
• Redo the block reach to a runenv param to avoid hard-coding test ending
