♻️ Reconcilation Statuses

[gluax]

For the reconciliation process what we should instead do is:

• agent reconcile RPC is short lived and returns an error, a requeue duration + status messages, or an OK
• control plane has a global reconcile loop that walks a reconcile queue
• env prepare (now apply) queues a reconcile for every agent

reasons:

• current reconcile logic dies if the rest request is closed
• current reconcile logic depends on long lived RPC contexts
• current reconcile logic does not showing show clear status
• new reconcile can show where things fail
• new reconcile has better code smell (a Reconcile trait or something and more modular code)
• new reconcile concepts are more battle tested in devops land
