Telemetry log: Add stack_trace field when given an exception

[TonyCTHsu]

What does this PR do?

Providing a class name of the exception is not very useful. Sending stack_trace help us identified the location is helpful

1. Add stack_trace field with reporting an exception
2. Obfuscate backtrace
3. Remove redundant debug level (The enriched data for debugging can be a risk and high data cardinality)

This is cool! Left a few notes

Just to doublecheck, does this format comply with the format that the other libraries are using?

We've had a few troubles with telemetry having mismatched formats between libs recently, so I think it's worth being extra careful here.

There is no specification about the format, but it is behaving as how DotNet is sending.

I possibly not for this PR, but it would be cool to perhaps leave stack entries from:

• The Ruby standard library -- paths starting with RbConfig::CONFIG.fetch("rubylibdir") (The profiler uses this to categorize Ruby code automatically as being from the standard library!)
• dogstatsd-ruby -- by perhaps asking rubygems where dogstatsd-ruby is, when available

[ivoanjo]

Left a recommendation for improving the test (I think the current one is too "mocky"), but otherwise it LGTM 👍
