Profiler: wrapper zap logger for datadog tracer agent

[nathantournant]

What does this PR do?

• [ ] Adds new functionality
• [X] Alters existing functionality
• [ ] Fixes a bug
• [ ] Improves documentation or testing

Please briefly describe your changes as well as the motivation behind them:

• The datadog logger interface is simple but did not fit the zap logger we used. This provides a wrapper that puts all tracer/profiler logs in our usual zap SugaredLogger, providing the usual tags / logging context, and very basic info/warn/error level parsing. The parsing allows to not receive tracer/profiler startup logs (and warnings) as errors, but set to the appropriate levels.
