* Remove out of place wait_online test param
* Cfgsync crate for testnet startup
* Config dispersal to node hosts
* Remove etcd dep and obsolete bash scripts
* Kzgrs test params in testnet
* Nodes listen on all interfaces
* Use value instead of variable in .env.testnet
* Reduce testnet logs verbosity
Debug logs are too verbose for long running node instances. If needed
users could manually adjust configuration in `testnet/*_config.yaml`
files without rebuilding the docker images.
