 Enhancement: Remove redundant config for invite_link_template
 
 This is to drop invite_link_template from the OCM-related config.
-The link template is still defined in a constant but not exposed
- in the config, as it depends on Mentix and should not be changed.
+Now the provider_domain and mesh_directory_url config options
+are both mandatory in the sciencemesh http service, and the link
+is directly built out of the context.
