The key functions added are: `bool enableForwarder(const String &domainName=emptyString, const IPAddress &dns=uint32_t)0)` If specified, `enableForwarder` will update the `domainName` that is used to match DNS request to this AP's IP Address. A non-matching request will be forwarded to the DNS server specified by `dns`. Returns `true` on success. Returns `false`, * when forwarding `dns` is not set, or * unable to allocate resources for managing the DNS forward function. `void disableForwarder(const String &domainName=emptyString, bool freeResources=false)` `disableForwarder` will stop forwarding DNS requests. If specified, updates the `domainName` that is matched for returning this AP's IP Address. Optionally, resources used for the DNS forward function can be freed.
