Add stack information when `stack_info` is set in logging integration.

[antonpirker]

Problem Statement

The stack information should be added to events send with the logging integration when stack_info=True is set.

Code like this should have a stack attached in the resulting event in Sentry:

logger.error(
    "Option %s set to %s. previous update channel: %s",
    key,
    value,
    channel,
    stack_info=True,
)

Solution Brainstorm

Check for the parameter in logging integration and add the stack information if parameter is True.

Some info from @untitaker :

exc_info=True should send the stack
specifically, it sends the current stack if sys.exc_info is None, otherwise it sends the current exc info
stack_info appears to be new in 3.2, we made the api design decisions with py2 in mind at the time

Hello @antonpirker,

Sentry's support just informed me that the stack trace is critical during the auto assignment of one event to the correct team as the path type rule is matched against all file paths of the stack.

Therefore I do have a lot of interest in resolving this issue. I did some research and I believe this is the method in need of modification. Any other places or any recommendation you find useful ?
