sun-api & sun-ui. added privacy fields

[edospadoni]

To comply with the new GDPR and Privacy regulations, portal accounts are required to enter some important information.

This PR adds the ability to insert fields into the account profile and prevents the creation of new hotspots if these fields are not filled in.

After merge execute:

ALTER TABLE accounts ADD `privacy_name` varchar(512) AFTER `email`;
ALTER TABLE accounts ADD `privacy_vat` varchar(512) AFTER `privacy_name`;
ALTER TABLE accounts ADD `privacy_address` varchar(512) AFTER `privacy_vat`;
ALTER TABLE accounts ADD `privacy_email` varchar(512) AFTER `privacy_address`;
ALTER TABLE accounts ADD `privacy_dpo` varchar(512) AFTER `privacy_email`;
ALTER TABLE accounts ADD `privacy_dpo_mail` varchar(512) AFTER `privacy_dpo`;
