Fixed arguments when using the rclcpp_component as a regular node in image_view

Related with this issue #824

I can also open PRs for the other nodes.

This seems very verbose - why can't we do:

auto args = rclcpp::init_and_remove_ros_arguments(argc, argv);
rclcpp::NodeOptions options;
options.arguments(args);

Which is what is generated if you use "rclcpp_components_register_node" (also why not just use that macro in the CMake?)

I also posted some comments in the original ticket - because I don't think this is actually needed - I think we just need to update documentation (somewhere) to reflect the changed way of sending parameters from the command line

[mikeferguson]

I do not think we want to merge this - as far as I can see, things are working as-is, as long as you follow the proper command line parameter specifications - and this doesn't appear to make any difference with the "remapping doesn't work when using compression" issue

[mikeferguson]

I believe that #851 is the correct approach to fix the remap issues
