Fix issues when starting with mainnet spec (#674)
* Update lcli to parse spec at boot, remove pycli

* Fix issues when starting with mainnet spec

* Set default spec to mainnet

* Ensure ETH1_FOLLOW_DISTANCE is in YamlConfig

* Set testnet ETH1_FOLLOW_DISTANCE to 16

* Set testnet min validator count

* Add validator count CLI flag to lcli contract deploy

* Extend genesis delay time
