* Remove network config store * Remove inline networks variable in network controller * Re-key network controller 'rpcTarget' to 'rpcUrl' * Require chainId in lookupNetwork, implement eth_chainId * Require chain ID in network form * Add alert, migrations, and tests * Add chainId validation to addToFrequentRpcList * Update public config state selector to match new network controller state * Use network enums in networks-tab.constants * Ensure chainId in provider config is current * Update tests
