In checkpoints/views.py, IndexView class, get_data() method, we list the checkpoints for a provider. After that, we iterate the checkpoints for that provider and get the provider using karbor client. This is not necessary: all the checkpoints are from the same provider, and even if they weren't, we could use karbor client to get each provider only once.
