[EPIC](carrier): Architecture design MFE carrier app

[edda]

Design architecture for MFE carrier app for operator dashboard apps.

Requirements:

• Deployable app that acts as the carrier for microfrontends
• MFE's are client side only
• All-in-one deployment: the deployment contains all MFEs, dependencies and import map bundled together so that app and deps can be loaded from the same webserver and there is no additional outside dependency (like a CDN)

Decisions needed:

• Carrier app: only client side or client + server architecture? --> POC
• Can we design the architecture such that both all-in-one deployment and dynamic loading of deps and/or MFEs from a CDN

Tasks:

• [ ] POC: all-in-one deployment for Greenhouse
