Spring Security Allow to configure the header value as a regular expression pattern in a request matcher

Expected Behavior

Allow to configure the expected header value as a regular expression pattern in a request matcher regardless of the http method. Similar to RegexRequestMatcher

Current Behavior

Currently, RequestHeaderRequestMatcher allows to match an expected header value as String.

Context

What are you trying to accomplish? Recently, came across a requirement which required to match the expected header value with a regular expression pattern, in-order to support custom token(s) with custom scheme(s) in Authorization header.

Thanks for reaching out @ShivakumarSwamy.

In this situation, I suggest creating a custom RequestMatcher. Within the Spring Security codebase, we have a similar situation where we match the "Bearer" scheme and for that we created a BearerTokenRequestMatcher.

I'm going to close this issue, but feel free to continue the discussion here if you run into problems.
