The configuration of repository formats is split up across two functions `validate_hash_algorithm()` and `validate_ref_storage_format()`. This is fine as-is, but we are about to extend the logic to also read default values from the config. With the logic split across two functions, we would either have to pass in additional parameters read from the config, or read the config multiple times. Both of these options feel a bit unwieldy. Merge the code into a new a new function `repository_format_configure()` that is responsible for configuring the whole repository's format. Like this, we can easily read the config in a single place, only.
