Validate email changes

[Gunni]

Anyone can set any email address in objects in ripe, suggestion is to send an email confirmation for such changes and not apply the change until the validation is complete.

Add into a queue pending creation/change until all emails are validated.

Hi @Gunni please email the DB-WG with your proposal for discussion.

In particular, Leo Vegoda recently made an NWI proposal on adjusting contact method requirements, and I think your proposal is relevant.
