NEO: by default, instantiate an admin node when there's a master node

Since commit ebc1636d ("instanciate a
single admin node, by default in the first subpartition"), there was
only 1 admin node (and 1 neoctl wrapper) and this was inconvenient if
the partition hosting it lost.

Only 1 admin node does monitoring.
