### Description `core.request.headers()` reads request headers with `ngx.req.get_headers()`, which stops at 100 (since #11140). Plugins that read headers through it, such as `request-validation`, `opa` and `forward-auth`, only see the first 100. Deployments that send more headers than that had no way to raise the limit. This PR adds `apisix.max_request_headers_readable` to `config.yaml`: - Default `100`, so behavior is unchanged. - `0` reads all headers. - The value is read once per worker and passed to `ngx.req.get_headers()`. #### Which issue(s) this PR fixes: Fixes # ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [x] I have added tests corresponding to this change - [x] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (If not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
