Fixes#5898
This PR does a few modifications for our webserver:
- Add a PortRange setting type.
- allow the --http.port option to accept a port range or a single port, when a range is provided Logstash will incrementally try this list to find a free port for the webserver.
- Logstash will report in the log which port it is using. (INFO LEVEL)
- It refactors a few methods of the webserver.
- It adds test for the binding of the ports.
Notes:
Port range can be defined in the logstash.yml or pass via the command line like this.
`bin/logstash -e 'input { generator {}} output { null {}}' --log.level verbose --http.port 2000-2005`
Fixes#5774

* overrides defaults of LogStash::Environment, BUT
* CLI flags override the yaml file
* several breaking changes to cli flag names (see config/logstash.yml)
* setting values are now type checked (see Setting and Settings classes)
Fixes#5313
