[AIRFLOW-2779] Add project version to license

The Incubator PMC requested that we add version information to the
license declarations to cope with the possibility of projects changing
licenses on us in the future.

Where possible I have worked out the version we are actually using, but
where that hasn't been possible and the project is still on the same
license (they all were) I have taken the latest version as of right now
