title: ReactQueryCacheProvider vs ReactQueryConfigProvider
body: <p>What is the difference between the <strong>ReactQueryCacheProvider</strong> and <strong>ReactQueryConfigProvider</strong> in react-query? I think the CacheProvider is a must due to it is the provider in order to use the context of react-query for the application. ConfigProvider seems to be an option in order to provide default configuration for the <strong>useQuery</strong>, the thing is that the configuration can be passed down to the CacheProvider.</p>
  <p>Someone can explain why to use the ConfigProvider besides the CacheProvider, and when should be it used?</p>
