Add support for terminate requests or configurable termination signal for running sessions

[benfiola]

Original discussion for context.

It appears that when terminating a running Python session - a SIGKILL is sent to the underlying process. While this does indeed kill the underlying process, it also prevents any sort of clean-up behavior (i.e., context managers, signal handlers, etc.).

It'd be great if I could either:

• Configure the signal being sent on session termination (i.e., a SIGTERM instead of a SIGKILL)
• Use terminate requests to more natively handle the problem

If either of these seem worthwhile, I'd be more than happy to submit a PR implementing the feature as I love the IDE, love this plugin and would love to contribute back.

@benfiola This probably needs to be updated over in debugpy/pydevd first to support it.

Here is the code where this is handled on terminateRequest from VS Code: https://github.com/microsoft/debugpy/blob/6735fcb073c0453d57eab25109a25385f610281b/src/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_api.py#L1083

This will need a setting added to the launch configuration (in python extension), and it will have to be passed through from debugpy to underlying pydevd where this is handled.
