cmd: dynamically load additional external commands

Instead of a fixed list of commands, a dynamic list of modules
residing within the `luarocks.cmd.external.<cmd_name>` in the Lua path
will be dynamically added. This allows extending LuaRocks with
additional commands.
Same for `luarocks.admin.cmd.external.<cmd_name>`.
