The HEAD method is conspicuously absent from the allowed methods list when `allow_methods="*"` is used. This doesn't really affect CORS preflight requests, as HEAD requests aren't preflighted by the browser, but it does prevent the actual cross-origin HEAD response from being read by the calling app. [This can catch people off-guard.](https://discuss.encode.io/t/for-cors-middleware-why-is-head-not-included-in-all-methods/939) This simply adds HEAD to the `ALL_METHODS` list in the CORS middleware module and includes some additional tests to validate the new behavior.
