Desculpe @pfaffman , mas receio que terei que remover essa nova tarefa rake em um PR futuro. Vamos estar hashando as chaves de API no banco de dados, então será fundamentalmente impossível recuperar uma chave existente.

> ⚠️This change is completely irreversible. Once the migrations are run, the pla… in text keys will be deleted from the database. Marking as a draft PR for now to avoid accidental merging, but this is ready for review.
API keys are now only visible when first created. After that, only the first four characters are stored in the database for identification, along with an sha256 hash of the full key. This makes key usage easier to audit, and ensures attackers would not have access to the live site in the event of a database leak.
Many of the changes in this diff are to implement the new post-create UI, which looks like:

From a security perspective, the key files to review are:
- `app/models/api_key.rb`
- `lib/auth/default_current_user_provider.rb`
- `db/migrate/20191128113434_add_hashed_api_key.rb`
- `db/post_migrate/20191128113435_remove_key_from_api_keys.rb`
@danielwaterworth I had some issues with `fab!` in the tests, because it 'refinds' the record from the database after the initial save. The keys are kept temporarily as instance variables, so this refind was causing the key to be lost. I set `refind:false` in these places, but would be interested if you know of a cleaner solution.
Substituí a tarefa get_or_create_master por uma tarefa create_master mais simples, que criará incondicionalmente uma nova chave. Se você quiser ter apenas uma chave, precisará manter o controle da chave no seu próprio sistema.
