As a server administrator I want all users share the same account information between instances of global scale nodes.

Describe the solution you'd like
The solution would be a way to force enable lookup server upload for certain account properties (e.g. Twitter, Website, Phone, Address).

Proposed technical solution
A config.php option like lookup_server.forced_property_scopes in which I may enter an associative array of properties to scopes (e.g. v2-private, v2-local, v2-federated, v2-published) which are to be force synchronized

'lookup_server.forced_property_scopes' => [
  'twitter' => 'v2-federated',
  'website' => 'v2-federated',
  'phone' => 'v2-federated',
  'address' => 'v2-federated',
]

Describe alternatives you've considered
There are no alternative options.

Start by reading config.php handling and tracing the lookup server upload path, especially where account-property scopes are selected. Define how lookup_server.forced_property_scopes should interact with the v2-private, v2-local, v2-federated, and v2-published scopes. Done means the configured properties are force-synchronized across instances without changing unconfigured behavior.
