When a HM is attached to a pool and a backend member in that pool
is a fake member (e.g. due to a typo on creation) the member remains
in ONLINE status. Basically this is due to the fact that there
isn't any LSP attached to that member and no Service_Monitor entries
will take care of it.
This patch checks inmediatelly after creation the member and update
the whole LB status to reflect this fake member that could help to
the user to identify quickly those fake members.
