[CLI] Workflows don't have tags but there is such column in CLI command output

[Anastasia Kuznetsova]

After user execute: mistral workflow-create <path-to-definition> he will see:

+--------+-----------+-----------------------------------------+----------------+
| Name | Tags | Created at | Updated at |
+--------+-----------+-----------------------------------------+----------------+
| wf2 | <none> | 2014-09-24 08:10:31.869032 | None |
| wf1 | <none> | 2014-09-24 08:10:31.871058 | None |
+--------+-----------+-----------------------------------------+----------------+

In the output there is column 'Tags', also there is a condition https://github.com/stackforge/python-mistralclient/blob/master/mistralclient/commands/v2/workflows.py#L38 where we check if tags is present or not.

But we don't have 'tags' property in workflow spec: https://github.com/stackforge/mistral/blob/150a1b9f0b73567d07506edcd8220c7541bc02e2/mistral/workbook/v2/workflows.py#L21 and we can't send tags via api call : https://github.com/stackforge/python-mistralclient/blob/master/mistralclient/api/v2/workflows.py#L30

eed to remove mentions about tags at all or add ability to use tags for workflows
