Looking like "create if not exists" logic is logging 404s to AppInsights

[brandonh-msft]

Repro steps

• Start a new Durable Functions workload on a brand new Function App instance (this requires additional tables above & beyond what the Functions Host creates)
• Observe the Live Metrics Stream for the App in question
• Notice many 404s as the orchestration gets up and running, creating its required tables, queues, and blob containers

I suspect there is CreateIfNotExists() calls going on for Tables, queues, etc that DF uses but those are bubbling up to the analytics; we should avoid this to avoid confusion.

Expected behavior

"Trapped" dependency exceptions shouldn't bubble up to the App Insights Exception logs.
