Title: Custom expirations for token flow OAuth

In order to take advantage of this change, you would extend Doorkeeper configuration with the custom_access_token_expiration lambda that takes a Doorkeeper application as an input. In our application, it would work as follows:

```ruby
Doorkeeper.configure do
custom_access_token_expiration do |app|
app.api_app.token_expiration
end
end
```
