Refractor/messaging

[theskumar]

Related to #2882

The messaging.py has quite a lot of code with multiple concerns, which can be easily divided into individual independent modules.

This refractor puts different messaging adapters into it's own modules for better maintainability and readability

[frjo]

Really liking these changes. Will make it easier and clearer to add new notification adapters.

Some tests are failing, will wait for the fix to them before deploying to test.

[theskumar]

Will look into the test.
