Fix JSON In Output for Configuration Groups

[Auston McReynolds]

Current:

$ trove configuration-show 2e560dda-2f6b-4f7a-baf2-e88d32870e0f
+----------------------+--------------------------------------+
| Property | Value |
+----------------------+--------------------------------------+
| datastore_version_id | 6f3b225b-c5c4-441f-bba1-71644a42d47c |
| description | None |
| id | 2e560dda-2f6b-4f7a-baf2-e88d32870e0f |
| name | Test2 |
| values | {u'amcrn': True} |
+----------------------+--------------------------------------+

Suggested:

$ trove configuration-show 2e560dda-2f6b-4f7a-baf2-e88d32870e0f
+----------------------+--------------------------------------+
| Property | Value |
+----------------------+--------------------------------------+
| datastore_version_id | 6f3b225b-c5c4-441f-bba1-71644a42d47c |
| description | None |
| id | 2e560dda-2f6b-4f7a-baf2-e88d32870e0f |
| name | Test2 |
| values | {"amcrn": true} |
+----------------------+--------------------------------------+

Will need to be fixed in configuration-create, configuration-show, and maybe more.
