rather them use person directly to Manage it. It might allow an user
  use more them one certificate to authenticate.

  An Unique reference is set whenever issue a certificate, this prevents
  conflicts if the transaction is restarted/retry after getNewCertificate
  is already called, since we cannot rollback the call to openssl.

  Include and improve test coverage

   if a duplicated certificate (with same CN) is eventually generated by a
   bug or external tool (for whatever reason), revoke should revoke them all.

Fix position update regarding the drone speed

These workflows on Person are useful for Japanese usecase only where
we use content translation for 'furigana' (pronunciation).

- rename `getSpeed` and `setSpeed` into respectively `getAirSpeed` and `setAirSpeed`
- add yaw, speed and climbRate in drones dictionary
- stop hardcoding leader's id
- remove setAltitude function
- use loiter with coordinates as parameters

- fix setAltitude:
  - Update `_last_target` when calling `setAltitude` otherwise `loiter` is broken.
  - Convert altitude parameter from absolute to relative value.

- fix getInitialAltitude
  - return absolute altitude

- fix getAltitudeAbs
