Changing fabricDNS might delete services after creating them

[lionello]

If the new fabricDNS resolves to the same URL as the old one (for example, one has implied tenant, other has explicit tenant), then the services will be deleted after being created/updated.

The solution is to make sure we normalize the fabricDNS before we compare the old and new and decided whether to replace the resource.
