## Issue Addressed #1992 and #1987, and also to be considered a continuation of #1751 ## Proposed Changes many changed files but most are renaming to align the code with the semantics of `--network` - remove the `--network` default value (in clap) and instead set it after checking the `network` and `testnet-dir` flags - move `eth2_testnet_config` crate to `eth2_network_config` - move `Eth2TestnetConfig` to `Eth2NetworkConfig` - move `DEFAULT_HARDCODED_TESTNET` to `DEFAULT_HARDCODED_NETWORK` - `beacon_node`s `get_eth2_testnet_config` loads the `DEFAULT_HARDCODED_NETWORK` if there is no network nor testnet provided - `boot_node`s config loads the config same as the `beacon_node`, it was using the configuration only for preconfigured networks (That code is ~1year old so I asume it was not intended) - removed a one year old comment stating we should try to emulate `https://github.com/eth2-clients/eth2-testnets/tree/master/nimbus/testnet1` it looks outdated (?) - remove `lighthouse`s `load_testnet_config` in favor of `get_eth2_network_config` to centralize that logic (It had differences) - some spelling ## Additional Info Both the command of #1992 and the scripts of #1987 seem to work fine, same as `bn` and `vc`
