Switch wikilambda_fetch/wikilambdaload_zobjects from Action API to REST API
Open, LowPublic
Actions

Description

For scalability. They don't need user-specific access, and we'll be hitting them quite a lot from client-side code.

  • Provide wikilambda_fetch equivalent via the REST API system (patch)
  • Add wikilambdaload_zobjects extras to above API (patch)
  • Add tests
  • Migrate function-orchestrator
  • Migrate front-end
  • Ensure new API is documented
  • Deprecate old Action API endpoints
  • Drop old Action API endpoints
