Full implementation for browsermod-proxy cli options

[triostones]

We saw 5 options after we run browsermob-proxy --help, but currently, there only implement one port option.

I think it would be better to implement all the options.

$ browsermob-proxy --help

--proxyPortRange [Integer]              The range of ports to use for proxies

                                          implementation (default: true)
