Provide official container that deploys to GCP CLI

Problem to solve

Similar to #31167 (closed)

we should add support for GCP deployments in a simple way.

Intended users

Teams implementing CD for the cloud

Further details

What it looks like in CircleCI orbs: Install the gcloud CLI, if not available

orbs:
  gcp-cli: circleci/gcp-cli@1.0.0
version: 2.1
workflows:
  install_and_configure_cli:
    jobs:
      - gcp-cli/install_and_initialize_cli:
          context: myContext
          executor: gcp-cli/default

Proposal

The docker image should:

• Initilize the gcloud CLI
• Install the gcloud CLI, if not available

deploy:
  stage: deploy
  image: gitlab/gitlab-gcpclient@SHA256
  script:
    - gcp ..."

FROM ubuntu:latest

ENV DEBIAN_FRONTEND=noninteractive

# Pull latest Cloud SDK release from Google Container registry
docker pull gcr.io/google.com/cloudsdktool/cloud-sdk:latest

# Verify the installation
docker run gcr.io/google.com/cloudsdktool/cloud-sdk:latest gcloud version

# Authenticate with the gcloud command-line tool by running:
docker run -ti --name gcloud-config gcr.io/google.com/cloudsdktool/cloud-sdk gcloud auth login
