New Docker build configuration

[schustmi]

Describe changes

This PR greatly increases the flexibility in which users can specify how ZenML builds the Docker image that is used to run their pipeline steps in remote orchestrators/step operators. Additionally, it reduces the code duplication of the Docker image building code that was found in many stack components by introducing a simple pydantic mixin PipelineDockerImageBuilder which all stack components can inherit from to easily build Docker images.

@safoinme I'm assuming that by build argument in this case you mean adding an additional line to the generated Dockfile.

Here would be one potential solution how to do that:

MyModelDeployer(BaseModelDeployer, PipelineDockerImageBuilder):
    @staticmethod
    def _generate_zenml_pipeline_dockerfile(
        parent_image: str,
        docker_configuration: DockerConfiguration,
        requirements_files: Sequence[str] = (),
        entrypoint: Optional[str] = None,
    ) -> List[str]:
        lines  = PipelineDockerImageBuilder._generate_zenml_pipeline_dockerfile(parent_image, docker_configuration, requirements_files, entrypoint)
        lines.append("EXPOSE 5000")
        return lines
