Always call updatedRowNotify in update

The problem in this change is detect al lthe updateRowNotify which should give bad results when called with same values.

I have changed a lot in various modules, most of them just mark the module as changed so they are not big deal.

The problematic which I have changed:
- server host to avoid to reprovision LDAP
- language to avoid special apache restart
- I have fixed the method _addToDelte in DNS tables to not store repeated values. This tables probably should have a common parent to avoid duplication
- The updateRowNotyfy method in Samba::Model::GeneralSettings already check values in the new and old row so it does NOT need conversion
- The updateRowNotify methods in network also seems to do checking so they seem safe
