make clearer distinction between init-network source file and the genesis file

[tzemanovic]

We use a source network TOML config to setup a network (using the init-network cmd). This file drives few different things:

• genesis file for the ledger
• config file for the ledger and intent gossiper
• global config file with the chain ID set to the created network's ID
• a setup directory for each genesis validator and one for all the other accounts that do not belong to any validator with:
  • genesis file for the ledger
  • config file for the ledger and intent gossiper
  • global config file with the chain ID set to the created network's ID
  • a wallet with generated addresses and keys (public keys can also be set in the source file, in which case we don't generate new ones)

This source network file is currently in the genesis module and we refer to it as "source genesis file" in some places, which is a bit confusing. We should refactor it out from the genesis module and give it a clearer name. Perhaps e.g. "network template".
