* SDK/Components/Python - Removed python_op in favor of python_component
* Added test for python_component + func_to_container_op.
* dsl.PythonComponent class is removed, because the metadata is now properly stored in the function object itself.

* Fixed the pipeline path string after merge.
* Addressed the PR comments.
Added more detailed explanation of base_image selection to the docstring.
* Removed extra empty lines
Made all SDK import relative so that they files always refer to the sibling files instead of the installed package. This makes debugging and development easier since you can be sure the correct files are used.
* Switching to map-based syntax for the arguments.
The list-based syntax is going to be deprecated.
* Switched to map-style arguments in _func_to_component_spec
* Updated testdata
