Consensus Engines Implementation: Aura (#911)
* Generalize BlockImport - move ImportBlock, BlockOrigin, ImportResult into shared sr-primitives - let Consensus provide and traits again - update consensus traits to latest development - implement traits on client::Client, test_client::TestClient - update RHD to use the new import_block API * Move ImportBlock into consensus-common * Send import notification in aura tests * Integrating aura into service * Make Signatures more generic * Aura Block Production with the given key * run aura on the thread pool * start at exact step start in aura * Add needed wasm blob, in leiu of better solutions. * Make API ids consistent with traits and bring upstream for sharing. * Add decrease_free_balance to Balances module * Encode `Metadata` once instead of two times * Bitops include xor * Upgrade key module. * Default pages to somewhat bigger. * Introduce upgrade key into node * Add `Created` event
