From 0826310b2a88a7846d11c8dff712fde0556e88fe Mon Sep 17 00:00:00 2001 From: Leonard Lyubich Date: Mon, 19 Sep 2022 19:39:03 +0400 Subject: [PATCH] [#1681] morph/netmap: Support `MaintenanceModeAllowed` config After recent changes in the NeoFS API protocol network configuration contains `MaintenanceModeAllowed` boolean flag. There is a need to support the config value in all NeoFS applications. Provide `Client.MaintenanceModeAllowed` method which read the config from the Sidechain. Extend `NetworkConfiguration` structure with `MaintenanceModeAllowed` field.
