internal/frontend: add an interface for creating request caches

This change adds a new Cacher interface that is used to create
middlewares for caching requests. This abstracts away the use of redis
so that the frontend doesn't depend on redis. The tests still depend
on redis for the 404 page testing logic, but the 404 page logic will
be moved out into a different package so those tests will go too.

The Expirer and Middleware interfaces are not present on the Cache
function so that the interface can be defined in package
internal/frontend without needing the dependency on the Middleware
package.

For golang/go#61399
