In order to help prevent excess logging of fields, it might be useful to allow either:
1. A application config setting for a repo to redact all fields by default. As an example:
```
config :friends, Friends.Repo,
database: "friends",
redact: :all
```
and/or
2. A schema attribute that does the same. As an example:
```
@redact :all
schema "users" do
# ...
end
```
I assume the implementation would be somewhere in these files:
