chg: [tlp] updating the new version of the traffic light protocol

published by FIRST.org

Some notes concerning the version 2.0 of the tlp taxonomy:

- A new tag is introduced `TLP:AMBER+STRICT` to clarify the restriction to
share only with your organisation.
- A new tag is introduced called `TLP:CLEAR` which seems to replace
`TLP:WHITE` as it disappears from the version 2.0 of the official TLP
document.
- The old tag `TLP:WHITE` is preserved in the taxonomy. As we don't have
any official reference in the version 2.0 about the compatibility with
`TLP:CLEAR`, we *assume* it's a synomym from the original `TLP:WHITE`.
- The old tag `TLP:EX:CHR` is also preserved in the taxonomy for
backward compatibility.

We strongly recommend any users using the tlp taxonomy in their tools to review
workflows and ensure that the new version 2.0 is taken into consideration.
