This is the first in a decently long series of commits to delete RegistryConfig
entirely and centralize all configuration in ConfigModule using Dagger. Once
this is done, then the text-based YAML configuration work can begin in earnest.
Note that the configuration settings from TestRegistryConfig will be moving
into ConfigModule.LocalTestConfig. This way they can be referred to in a static
context from test and test utility helpers, rather than having to be injected
everywhere, which we don't typically bother with for tests.
