Dependency overhaul

[tokebe]

Completely overhauls dependency handling such that Retriever is able to catch and report dependency outages and contine trucking without them as best it can.

Highlights:

• Fallback from one tier to another (disableable)
• /asyncquery handling even when job state storage is unavailable
• Optable management when Redis is down
• Warnings all around
• HTTP 424 when an endpoint is truly unavailable (with dependency outage details in response)
• /monitor endpoint for a visual overview of status and jobs
• Various fixes
