anonymous friendly tahoe create-node/create-client

subset of tasks from ​https://tahoe-lafs.org/trac/tahoe-lafs/ticket/517#comment:29

• change tahoe create-client to make a tahoe.cfg that doesn't listen on anything
• change "tahoe create-node" to require --listen and --location
• change "tahoe create-node" to handle the new Tor/I2P arguments, once we figure out how they should be spelled

rough sketch of create-node cli here: ​https://github.com/david415/tahoe-lafs/tree/2490.anonymous-create-node-client.0

[user@tahoe-dev1 tahoe-lafs]$ ./bin/tahoe create-node -h

Usage: tahoe [global-options] create-node --listen=... --location=... [options] [NODEDIR]
(use 'tahoe --help' to view global options)

Options:
      --no-storage   Do not offer storage service to other nodes.
  -C, --basedir=     Specify which Tahoe base directory should be used. This has
                     the same effect as the global --node-directory option.

  -n, --nickname=    Specify the nickname for this node.
  -i, --introducer=  Specify the introducer FURL to use.
  -p, --webport=     Specify which TCP port to run the HTTP interface on. Use
                     'none' to disable. [default: tcp:3456:interface=127.0.0.1]
      --listen=      Specify a Twisted server endpoint descriptor string to be
                     used for our storage service listener.
      --location=    Specify a foolscap client connection hint string to
                     advertise as our storage service.
      --version      
      --help         Display this help and exit.
