Add a missing key on DrydockLease
Summary: Depends on D18734. See PHI176. We run this query on the main Drydock lease web UI, among other places. There is currently no `status` key which can satisfy it.
Test Plan:
Viewed Drydock lease page to get the query.
Ran ##explain SELECT * FROM `drydock_lease` WHERE (status IN ('pending', 'acquired', 'active')) ORDER BY `id` DESC LIMIT 101;## before and after the change.
I don't have a ton of leases locally so the un-key'd EXPLAIN isn't //that// bad, but still shows that we're getting a better key. Before:
```
mysql> explain SELECT * FROM `drydock_lease` WHERE (status IN ('pending', 'acquired', 'active')) ORDER BY `id` DESC LIMIT 101;
+----+-------------+---------------+-------+---------------+---------+---------+------+------+-------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+---------------+-------+---------------+---------+---------+------+------+-------------+
| 1 | SIMPLE | drydock_lease | index | NULL | PRIMARY | 4 | NULL | 101 | Using where |
+----+-------------+---------------+-------+---------------+---------+---------+------+------+-------------+
1 row in set (0.00 sec)
```
After:
```
mysql> explain SELECT * FROM `drydock_lease` WHERE (status IN ('pending', 'acquired', 'active')) ORDER BY `id` DESC LIMIT 101;
+----+-------------+---------------+-------+---------------+------------+---------+------+------+---------------------------------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+---------------+-------+---------------+------------+---------+------+------+---------------------------------------+
| 1 | SIMPLE | drydock_lease | range | key_status | key_status | 130 | NULL | 5 | Using index condition; Using filesort |
+----+-------------+---------------+-------+---------------+------------+---------+------+------+---------------------------------------+
1 row in set (0.00 sec)
```
