Adds logging support for python debug adapter

[karthiknadig]

For #8106

• Pull request represents a single change (i.e. not fixing disparate/unrelated things in a single PR)
• Title summarizes what is changing
• Has a news entry file (remember to thank yourself!)
• Appropriate comments and documentation strings in the code
• Has sufficient logging.
• Has telemetry for enhancements.
• Unit tests & system/integration tests are added/updated

@kimadeline I need some advise on testing the logger.

@DonJayamanne I need some advise on testing DebugSessionLoggingTracker. I feel like the right way to test it would be to use an end to end test.

Some typescript suggestions but other than it looks good to me 👍
