ignoring invalid cors headers on Ingress "*"

[a180285]

Description of the problem

I want to set CORS access-control-allow-headers to "*". but I got this errror.

ignoring invalid cors headers on Ingress "xx/xx" *

base on description here. "*" should be valid headers.

* (wildcard)
The value "*" only counts as a special wildcard value for requests without credentials (requests without [HTTP cookies]

(https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies) or HTTP authentication information). In requests with credentials, it is

 treated as the literal header name "*" without special semantics. Note that the [Authorization](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Authorization) header can't be wildcarded and always needs to be listed explicitly.

Expected behavior

Steps to reproduce the problem

1. add annotation of haproxy-ingress.github.io/cors-allow-headers: '*' to ingress

Environment information

HAProxy Ingress version: v0.xx
image version: quay.io/jcmoraisjr/haproxy-ingress:v0.14.2

Root cause

Code corsHeadersRegex are hard coded. and without "*".
