datastore info on show instance should not show a dict

[Craig Vyvial]

This is what it looks like now...

$ trove show bbe186a2-9a21-4ecf-9cf7-16623993231f
+-----------+-------------------------------------------------------------+
| Property | Value |
+-----------+-------------------------------------------------------------+
| created | 2013-11-22T18:51:20 |
| datastore | {u'version': u'mysql_test_version', u'type': u'Test_Mysql'} |
| flavor | 7 |
| id | bbe186a2-9a21-4ecf-9cf7-16623993231f |
| ip | 10.0.0.3 |
| name | florida |
| status | ACTIVE |
| updated | 2013-11-22T18:51:27 |
| volume | 1 |
+-----------+-------------------------------------------------------------+

But should be more like...

$ trove show bbe186a2-9a21-4ecf-9cf7-16623993231f
+-----------+-------------------------------------------------------------+
| Property | Value |
+-----------+-------------------------------------------------------------+
| created | 2013-11-22T18:51:20 |
| datastore_version | mysql_test_version |
| datastore_type | Test_Mysql |
| flavor | 7 |
| id | bbe186a2-9a21-4ecf-9cf7-16623993231f |
| ip | 10.0.0.3 |
| name | florida |
| status | ACTIVE |
| updated | 2013-11-22T18:51:27 |
| volume | 1 |
+-----------+-------------------------------------------------------------+
