Notification of user death to the Wallet Provider

[grausof]

According to

eudi-wallet-it-docs/docs/en/credential-revocation.rst

Line 79 in 073ac6a

.. note::

it is necessary to define the technical specifications of how the communication of the user's death occurs from the pid provider to the Wallet Provider for the revocation of the Wallet Instance as foreseen in the guidelines.

@grausof, we identified two options:

• Using current mechanism based on status assertion: when the user dies the status assertion will contain the reason about revocation (i.e death of the user).
• Defining a new PDND API e-Service provided by Wallet Provider and used by Pid Provider to notify this event.

In the first case no changes are required while in the second case it is necessary to define the new endpoint.

@m-basili I think we should think about the second case since the wallet provider has no way to access the status assertion without the user's proof of ownership.
