When an activity failure happens, the SQL row is updated:
- date is set to a future value, so the activity does not get retried
  immediately, in the expectation that what caused the failure may have
  cleared by that point.
- retry is incremented, to allow limiting the total number of retries
- priority is incremented

This last point seems harder to justify, and seems redundant with the date
increase. In the context of processing node families and with a steady
influx of similar activities at a base priority level, such priority
increment can postpone the victim activity execution to an arbitrarily
large amount of time, which is undesirable.
So, remove this increment.

- drop console logs
- update api doc
- refine init map coordinates
- crash drone if logic is empty
- jslint

sqlvar type="nb" was broken by sqlvar patch without being noticed,
thus test is required. See commit ebdc34d4.

   Redirect with error level, to display the notification properly displayed as error

  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.
