feat: add support for logging extras #94
Description
Is your feature request related to a problem? Please describe.
Currently the .NET runtime does not support adding extra keys to a specific logging. Here is the Python implementation -> https://awslabs.github.io/aws-lambda-powertools-python/latest/core/logger/#extra-parameter
Describe the solution you'd like
I would like to be able to add extra fields to logging and have examples on documentation.
