Create remote development workspace for GDK to replace GitPod

Context: GitPod is sunsetting their Saas offering (GitPod Classic). https://www.gitpod.io/blog/introducing-gitpod-flex-faq. We need to create an alternative remote development environment for first time contributors and other people not comfortable or able to proceed with local or docker installation.

Actions:

• Competitive research - dogfood GitLab Workspaces
• "Test out" current state
  • Deploy sandbox workspaces environment to follow docs and get familiar with the current state of the feature
• POC
  • Get a GCP project created for hosting workspaces cluster
  • Get/assign a DNS domain for the cluster purposes
    • gitlab-community.dev?
  • Build out a POC cluster following IAC principles
    • Configure sudo access
  • Test cluster internally
  • Add test users to POC cluster
    • Core team
    • others?
• Implementation
  • Figure out any gaps for 'main go live'
  • Fill in gaps
  • Add gitlab-community to cluster agent access
  • Set up feedback issue
• Documentation
  • Add 'getting started' page in docs
