Add ability to generate config and genesis for testnet and mainnet

[omritoptix]

Currently we generate minimal genesis template from each specific repo by running a specific script.

Roller should have the ablity to generate gensis for the rollapp creator with specification if its for testnet or mainnet where the 2 may differ by sane defaults.

e.g on mainnet we may have 24 hours govereance, while on testnet we may have 5 minutes.

DOD:

1. notion table with each param, column for mainnet, testnet and its agreed upon value.
2. ability to run roller genesis generate [vm ][environment] and get the relevant genesis tempalte
