Add initial set of telemetry events

[Charles-Gagnon]

Added initial set of events - focusing on a few key metrics :

• Overall and feature-specific usage
• Query performance
• Errors*

*Note that for errors all we capture is the name of exception type (e.g. InvalidOperationException). No PII is gathered for any of the events.

List of the non-Error events added :

• Creation of handlers (one is created once per binding)
• Input conversions being performed (maps to number of invocations of the binding)
• Output binding table info cache hit/miss
• Output binding execution trace and timings - one event for each sub-query (case sensitivity, column definitions, primary keys)
• Output binding upsert perf (including # of batches inserted)

Please check the test failure. Looks good otherwise; I appreciate your thoroughness.
