If i provide the --datastore option:
$ trove --debug configuration-parameter-show mysql-5.5 max_connections --datastore mysql
+------------------+-----------------+
| Property | Value |
+------------------+-----------------+
| max | 65535 |
| min | 1 |
| name | max_connections |
| restart_required | False |
| type | integer |
+------------------+-----------------+

In the case of the missing --datastore parameter, it should probably return something like this:

ERROR: The datastore name or id is required to show the information on a configuration parameter

This looks like a bug for python-troveclient, but not Trove at all.

    Fix error with configuration-parameter-show

    According bug description, there will be an error when
    use configuration-parameter-show without version_id
    and datastore. To fix this problem, I add an judgement
    for use the cmd without parameter datstore and
    datastore_version not like an uuid.

    Now in such a case, the cmd will has an exception info.
