Migration of Pipelines-Components to Kubeflow SDK with git submodule

[EncHawk]

The pipelines repository needs to be migrated into the Kubeflow SDK to avoid the use of multiple packages and allowing a unified presence for all the packages in the SDK repository as discussed here

Approach

The approach, as discussed in the call, will be to include the Kubeflow Pipelines repository as a submodule, making it easier to use in the SDK, without needing additional installation as a package.

@LukaszCmielowski yup, working on it. failing tests on pipelines/components. since the plan is to omit the pyproject.toml file, there are a few errors that im fixing.
