Add application-insights debug cli

[bmc-msft]

Quite frequently, I find myself needing to perform queries against an instance's application insights log. Rather than continually going into the portal, this exposes the query API via the CLI.

TODO:

• Add recording the instance specific appId for application insights to the ARM template for the Azure Function
• Add said appId to the onefuzz info get
• Update the debug code to use said "appId" from info.get() instead of os.environ['APP_ID']

The following example use searches for the keyword "scaleset". Then using jmespath, prints the first message.

❯ onefuzz --endpoint https://pr-check-e250f3223ada4b2fb84a807c33063dfb.azurewebsites.net debug logs keyword scaleset --query 'PrimaryResult[0].message'
"Executed 'Functions.scaleset' (Succeeded, Id=bc1cb88e-9508-4e1f-b4b9-15d18ded3439, Duration=23ms)"
