Attachable containers they are tasks with no service associated
their cleanup was not done properly so it was possible to have
a leak of their name resolution if that was the last container
on the network.
Cleanupservicebindings was not able to do the cleanup because there
is no service, while also the notification of the delete arrives
after that the network is already being cleaned

* Service Discovery reuse name and serviceBindings deletion
- Added logic to handle name reuse from different services
- Moved the deletion from the serviceBindings map at the end
of the rmServiceBindings body to avoid race with new services

* CleanupServiceBindings to clean the SD records
Allow the cleanupServicebindings to take care of the service discovery
cleanup. Also avoid to trigger the cleanup for each endpoint from an SD

changed the ipMap to SetMatrix to allow transient states
Compacted the addSvc and deleteSvc into a one single method
Updated the datastructure for backends to allow storing all the information needed
to cleanup properly during the cleanupServiceBindings
Removed the enable/disable Service logic that was racing with sbLeave/sbJoin logic
Add some debug logs to track further race conditions

- Do not relay on software flags to decide when to create the
virtual service. Instead query the kernel for presence.
So that it cannot happen that a real server creation
fails because the virtual server is missing.
