Fix typo in oneadmin's StratusLab configuration
Update oned component in Quattor configuration hierarchy

The NCM component for OpenNebula was updated several months ago in
commit 16af450 but the modifications were not applied under the Quattor
configuration hierarchy.
Remove hardcoded marketplace protocol
Remove all references to unused local NCM modules

All references to the local NCM modules Claudia, Ganglia and libvirtd
were removed from the repository.

Claudia was no longer supported by StratusLab, and Ganglia and libvirtd
were moved to official modules repository. Specific Qemu configuration
was extracted from libvirtd configuration and put in another template.
