provider: Load providers at provider driver registration time

Load all saved providers that have the same type as the provider
driver being registered. While looking through the storage dir
for directory entries starting with 'provider_', the respective
settings file needs to be opened in order to check the type.
Since the settings file is already opened, load all other settings
as well with the help of the previously factored out functions.
