Refactor code fore blockchain network management (#1691)
* [settings] remove unused `NetworkState` class * [config] introduce network enum for different networks (it is not used yet) * remove obsolete fields of endpoint data and settings store * [settingsStore] remove obsolete endpointList observable * [settingsStore] switch from EndpointData to the new Network enum * remove obsolete hardcoded encointer endpoints * [consts] rename `ipfs_gateway_local` to `ipfsGatewayLocal` * [consts] remove obsolete `faucetAmount` * fix: endpoint getters * [settings] fix: remove obsolete EndpointData class * [encointer_store_test] fix: serialization roundtrip * [LocalStorage] disambiguate between removeObject and removeKV * fmt * [settings] re-introduce default endpoint test * [config/networks] proper enum ordering and make clear that we are not referring to the relaychains * [config/networks] rename info to id * [config/networks] add comment about removing `value` * [mockData] remove obsolete `unitTestEndpointInfo` * [settings] rename misnomer `endpoint` to `currentNetwork`
