Actual results:
TASK [Create LVs with specified size for the VGs] ****************************************************************************************************
failed: [node] (item={u'lv': u'some_thinpool', u'size': u'', u'extent': u'100%FREE', u'vg': u'some_vgname'}) => {"failed": true, "item": {"extent": "100%FREE", "lv": "some_thinpool", "size": "", "vg": "some_vgname"}, "msg": " No command with matching syntax recognised. Run 'lvcreate --help' for more information.\n Nearest similar command has syntax:\n", "rc": 3}

As you can see, the 'size' is not specified. Seems the lvcreate.yml playbook doesn't implement the default size as described in the Admin Guide.
Expected results:
Would expect gdeploy to provide defaults per the Admin Guide and successfully create the LV.
