IaC configurability for flow schedules and variables

[sergiimk]

Objective

• minimize the scope of changes as much as possible
• Use SQLite DB in single-tenant local workspace
• Contexts (local/remote) and switching in CLI
• CRUD commands for manifests/objects
• Upsert API for objects other than datasets
  • Provide upsert-style API for dataset env vars #139

Notes

• Kubernetes-like objects?
  • great for ODF spec
  • apply via tool
  • templating would require re-inventing something like helm + helmfile
• Terraform modules?
  • Templating & instancing
  • State is stored separately
• Use kubernetes itself
  • Kamu objects as CRDs
  • Reuse secrets providers and other integrations
  • Reuse tooling (kubectl, helm templating, ide integrations...)
• Design how secret management will work
