This PR adds the first tests for `stale-if-error` logic in `HttpCache`.
It also fixes an observation from #24248: For responses that have been cached as `public` with an `ETag` but without a lifetime, in case of an error the stale response will be served forever (= as long as the error persists), even beyond the configured `stale-if-error` grace period.
Furthermore, it tries to improve compliance with RFC 7234: Stale responses must not be sent (under no condition) if one of
* `no-cache`
* `must-revalidate`
* `proxy-revalidate` or
* `s-maxage` (sic) is present.
This can be found in the corresponding chapters of Section 5.2.2 for these directives, but is also summarized in [Section 4.2.4](https://tools.ietf.org/html/rfc7234#section-4.2.4) as
> A cache MUST NOT generate a stale response if it is prohibited by an explicit in-protocol directive (e.g., by a "no-store" or "no-cache" cache directive, a "must-revalidate" cache-response-directive, or an applicable "s-maxage" or "proxy-revalidate" cache-response-directive; see Section 5.2.2).
Because disabling of `stale-if-error` for `s-maxage` responses probably has a big impact on the usefulness of that feature in practice, it has to be enabled explicitly with a new config setting `strict_smaxage` (defaulting to `false`).

Just noticed that when a response has been cached that is `public` and has an `maxAge` but does _not_ provide `Last-Modified`, the validation subrequest will have an empty `If-Modified-Since` header value.

* Added a hardcoded day 01 in order to output the proper month November
which is the correct EOL and EOM month.
* \DateTime::createFromFormat('mY') will output December for every month
where day 31 exists.

sometime the http server returns a `s-maxage=3` header (https://travis-ci.org/symfony/symfony/jobs/569326531)
This PR fixes tests to allow both 2 and 3
