Cache 301 redirect with a default timeout

[gajus]

Currently 301 redirects are not cached at all unless the website returns a satisfying cache-control header. This is not how browsers work.

There should be a setting to cache 301 redirects for an arbitrary default time.

The spec says:

https://tools.ietf.org/html/rfc7231#section-6.4.2

A 301 response is cacheable by default; i.e., unless otherwise
indicated by the method definition or explicit cache controls (see
Section 4.2.2 of [RFC7234]).

So caching it would be a good idea indeed. It can probably be similar setting to the default cache time heuristic.
