FromCookies support for RequestAuthentication

[kebe7jun]

(This is used to request new product features, please visit https://discuss.istio.io for questions on using Istio)

Describe the feature request
Envoy's JwtProvider already supports the FromCookies field, which will be used in some scenarios, so hopefully Istio supports this parameter.

Describe alternatives you've considered
Use envoyfilter patch http_filter manually.
