The AlterTag task can be used to change the description of a tag.
To ensure that you are not over-writing another user's changes, run dbcloudcmd -v describe task to get the time the object was last modified. Specify this value as the object_updated parameter. If the cloud has been altered
since the specified time, the task fails with an error. If this occurs, run the task again after re-running dbcloudcmd -v describe task.
