Add --cookie and --cookie-param options to ronin http

[postmodern]

The ronin http command should have --cookie "..." and --cookie-param NAME=VALUE options, similar to ronin-vulns scan. Feel free to copy the code and specs from ronin-vulns. The options should populate a @cookie instance variable of type Ronin::Support::Network::HTTP::Cookie and pass it to Support::Network::HTTP.request(...) and HTTPShell.start(...). The new options should also be added to the Ronin::CLI::Commands::Http class documentation and the man/ronin-http.1.md man-page.
