chain-spec: getting ready for native-runtime-free world (#1256)
This PR prepares chains specs for _native-runtime-free_ world. This PR has following changes: - `substrate`: - adds support for: - JSON based `GenesisConfig` to `ChainSpec` allowing interaction with runtime `GenesisBuilder` API. - interacting with arbitrary runtime wasm blob to[ `chain-spec-builder`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/bin/utils/chain-spec-builder/src/lib.rs#L46) command line util, - removes [`code`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/frame/system/src/lib.rs#L660) from `system_pallet` - adds `code` to the `ChainSpec` - deprecates [`ChainSpec::from_genesis`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/client/chain-spec/src/chain_spec.rs#L263), but also changes the signature of this method extending it with `code` argument. [`ChainSpec::builder()`](https://github.com/paritytech/substrate/blob/20bee680ed098be7239cf7a6b804cd4de267983e/client/chain-spec/src/chain_spec.rs#L507) should be used instead. - `polkadot`: - all references to `RuntimeGenesisConfig` in `node/service` are removed, - all `(kusama|polkadot|versi|rococo|wococo)_(staging|dev)_genesis_config` functions now return the JSON patch for default runtime `GenesisConfig`, - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed, - `cumulus`: - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed, - _JSON_ patch configuration used instead of `RuntimeGenesisConfig struct` in all chain specs. --------- Co-authored-by: command-bot <> Co-authored-by: Javier Viola <javier@parity.io> Co-authored-by: Davide Galassi <davxy@datawok.net> Co-authored-by: Francisco Aguirre <franciscoaguirreperez@gmail.com> Co-authored-by: Kevin Krone <kevin@parity.io> Co-authored-by: Bastian Köcher <git@kchr.de>
