Specs
stop() :: :ok | {:error, :not_allowed | :not_found}
Turns a distributed node into a non-distributed node.
For other nodes in the network, this is the same as the node going down.
Only possible when the node was started with Node.start/3, otherwise
returns {:error, :not_allowed}. Returns {:error, :not_found} if the
local node is not alive.
