Bug 1127534

Description of problem:

The unique key uc_user_id on lab_controller is not defined in the model code.

How reproducible:

always

Steps to Reproduce:
1. run beaker-init against a fresh db
2. login to db and show create table lab_controller

Actual results:

| lab_controller | CREATE TABLE `lab_controller` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `fqdn` varchar(255) DEFAULT NULL,
  `disabled` tinyint(1) NOT NULL,
  `removed` datetime DEFAULT NULL,
  `user_id` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `user_id` (`user_id`),
  UNIQUE KEY `fqdn` (`fqdn`),
  CONSTRAINT `lab_controller_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `tg_user` (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |

Expected results:

| lab_controller | CREATE TABLE `lab_controller` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `fqdn` varchar(255) DEFAULT NULL,
  `disabled` tinyint(1) NOT NULL,
  `removed` datetime DEFAULT NULL,
  `user_id` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `uc_user_id` (`user_id`),
  UNIQUE KEY `fqdn` (`fqdn`),
  KEY `user_id` (`user_id`),
  CONSTRAINT `lab_controller_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `tg_user` (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8 |

Additional info:

Other than adding the missing definition in the model code, we also need to use alembic to create a revision for those instances that have already been upgraded to beaker 0.17.
