ENHANCEMENTS:

• client: New UnixSocketConfig option in ClientConfig to support making the client's Unix sockets group-writable [GH-277]

ENHANCEMENTS

• client: New runner.Runner interface to support clients providing custom plugin command runner implementations [GH-270]

• client: Add ID() method to Client for retrieving the pid or other unique ID of a running plugin [GH-272]
• server: Support setting the directory to create Unix sockets in with the env var PLUGIN_UNIX_SOCKET_DIR [GH-270]
