Make it possible to withdraw certificates

[Soped42]

Description

In case of errors in the system related to already issued certificates, we need a mechanism for bringing the wallet and regisry into a correct state.

Example: We issue a certificate with too much produced energy which we need to withdraw. See the diagram from Energy Track and Trace:

The solution requires clear business case analysis, as there are som considerations related to how the market actors will experience a withdraw of a certificate.

If the Certificate has been transfered or claim fully or partially there is a need to consider how to inform the market actors.

• Who do we notify and how?
• How do we counter the wrong certificate? Do we "consume" some power with a correction consumption certificate if we need to remove power?
  Do we issue an additional certificate in the same time period if we need more power?
  Do we withdraw and issue a new correct certificate and execute all previous transaction such as claim, withdraw etc.?

Basic Example

It must be possible to withdraw a certificate to correct the available amount of energy in the grid.

Drawbacks

Not implementing withdraw leaves us in a situation where errors cannot be corrected in the market.
