CORS. Dynamic set access-control-allow-headers from access-control-request-headers

Title: Feature request. Set access-control-allow-headers dynamically from access-control-request-headers with rule

Description:

Now cors filter set response header access-control-allow-headers to allow_headers value from config. Wildcard not support/work in access-control-allow-headers in browser if access-control-request-headers set in request. Best practice resolve this problem, set access-control-allow-headers to value access-control-request-headers if wildcard in config.

Will this implement in envoy? Thanks.
