Fact importing fails when trying to import facts with large data:

Fact etc_services_fact could not be imported because of Mysql2::Error: Data too long for column 'value' at row 1: INSERT INTO `fact_values` (`value`, `fact_name_id`, `host_id`, `created_at`, `updated_at`) VALUES ('LONG-DATA', 789, 11085, '2017-01-10 02:39:07', '2017-01-10 02:39:07')

The column 'value' is of type TEXT, to fix this it could be increased to MEDIUMTEXT or even LONGTEXT.
