Add support for debug log level

[soote1]

We (global-devops team) would like to enhance our logging strategy in all our lambda functions. To achieve that, we would like to add logging instructions with different logging levels and control them via an environment variable. We noticed that the package supports the latter requirement. However, with regard to logging levels, we realized that it doesn't support DEBUG. While working on the required changes to provide such feature, we realized that the logic to check if the data should be logged in CommonLogger.log() was incorrect. Basically, the **kwargs were not being propagated to CommonLogger.__should_log() method. Thus, CommonLogger.__get_log_level() method was returning an incorrect value.

That said, this PR provides a set of changes to:

• Add support for DEBUG log level
• Fix an issue while checking if the CommonLogger should log the given data.
