Add timeline management features to the cli client

[jkppr]

On the timesketch slack channel, we recently ran into a problem where it would have been useful to delete timelines via the CLI client.

Feature Request: Add support for timeline management features like

• [x] renaming
• [x] deleting
• [x] changing color to the cli client.
