special
Initialization of the GCP ZenML integration.
The GCP integration submodule provides a way to run ZenML pipelines in a cloud
environment. Specifically, it allows the use of cloud artifact stores
and provides an io module to handle file operations on Google Cloud Storage
(GCS).
The Vertex AI integration submodule provides a way to run ZenML pipelines in a Vertex AI environment.

This is an intermediary representation of the pipeline which is then

-------------
Before this method is called the `prepare_pipeline_deployment()` method
builds a Docker image that contains the code for the pipeline, all steps
the context around these files.
Based on this Docker image a callable is created which builds
container_ops for each step (`_construct_kfp_pipeline`). The function
`kfp.components.load_component_from_text` is used to create the
`ContainerOp`, because using the `dsl.ContainerOp` class directly is
deprecated when using the Kubeflow SDK v2. The step entrypoint command
with the entrypoint arguments is the command that will be executed by
the container created using the previously created Docker image.
This callable is then compiled into a JSON file that is used as the
intermediary representation of the Kubeflow pipeline.
This file then is submitted to the Vertex AI Pipelines service for
execution.

deployment: The pipeline deployment to prepare or run.
stack: The stack the pipeline will run on.

Based on this Docker image a callable is created which builds
container_ops for each step (_construct_kfp_pipeline). The function

ZenMLGCPAWSExternalAccountCredentials (Credentials)
An improved version of the GCP external account credential for AWS.
The original GCP external account credential only provides rudimentary support for extracting AWS credentials from environment variables or the AWS metadata service. This version improves on that by using the boto3 library itself (if available), which uses the entire range of implicit authentication features packed into it.
Without this improvement, sts.AssumeRoleWithWebIdentity authentication is
not supported for EKS pods and the EC2 attached role credentials are
used instead (see: https://medium.com/@derek10cloud/gcp-workload-identity-federation-doesnt-yet-support-eks-irsa-in-aws-a3c71877671a).
