Storage node should not provide NeoFS Object API service when it is under maintenance. Declare `Common` service that unifies behavior of all object operations. The implementation pre-checks if node is under maintenance and returns `apistatus.NodeUnderMaintenance` if so. Use `Common` service as a first logical processor in object service pipeline.
