📄 Description

In addition to being too small for real-world use, the small default cache sizes (100 entries each) are impacting some testing I'm doing. This PR introduces two new (optional) recursor store configuration options: ns_cache_size and record_cache_size, which default to 1024 and 1048576, respectively, if they are not specified in the config file.
