Add possibility to set max header size for requests

### Current Behavior

Referring to discussion https://github.com/DependencyTrack/dependency-track/discussions/3384

It's currently not possible to set the max header size for embedded Jetty server.
In class EmbeddedJettyServer public method main (package alpine.embedded) there's no way to to set this configuration property by CLI argument or config file.

### Proposed Behavior

Proposal:

---
public static void main(String[] args) throws Exception {
---
CliArgs cliArgs = new CliArgs(args);
---
Server server = new Server();
HttpConfiguration httpConfig = new HttpConfiguration();
httpConfig.addCustomizer(new ForwardedRequestCustomizer());
HttpConnectionFactory connectionFactory = new HttpConnectionFactory(httpConfig);
ServerConnector connector = new ServerConnector(server, new ConnectionFactory[]{connectionFactory});
connector.setHost(host);
connector.setPort(port);
---

I would recommend to add a CLI arg and pass it to method httpConfig.setRequestHeaderSize(cliArgs.switchIntegerValue("-maxRequestHeaderSize", 8192));
