Compile and execute pipelines simultaneously

[speg03]

For example, the submit command can be executed by specifying options related to compilation.

$ kfp-toolbox submit --py /path/to/pipeline.py --function pipeline

Currently, the pipeline function is compiled first, then the pipeline is executed by specifying a compiled package file.

$ dsl-compile-v2 --py /path/to/pipeline.py --function pipeline --output ./pipeline.json
$ kfp-toolbox submit -f ./pipeline.json

Since the compiled package file is not always necessary, it should be output to a temporary directory if the output option is not specified.

If no Python file is specified, it tries to import the function name as it is. The specification of Entry points may be helpful for how to specify the function.

If no function name is passed in dsl-compile-v2, the first pipeline function defined in the specified python file is adopted.
