Description

This effort covers the implementation of the Validator Set Realm in gno, that has a standard set management API. Validator sets should be managed by the 2/3+ majority of voting power.

An example of the API (not extensive):

• GetSet() - returns the validator set
• AddValidator(…) - adds a validator to the set
• RemoveValidator(…) - removes a validator from the set

This effort is blocked by: #1823

Successful outcome of this effort:

• A validator set Realm is created, with a standard set management API
• The validator set Realm is predeployed on every chain initialization (genesis)
