Add Notification service for task complations in api

[berkingurcan]

Add e-mail notification services for api. So after the successful completion of the tasks, it will inform the user.

In the fast api, there are tasks:

Manuals:

• Run task for everyone
• Run task for specific user

Scheduled, automatized:

• Scheduled task

So, in order to get information about these tasks are successful or encountered an error, @CristinaEche the admin has to investigate terminal logs. It is not the best UX.

In order to create better UX, after successful or unsuccessful completion of each task, we need to implement notification service.

TODOs

• Research, discuss with me and decide proper notification service(e-mail etc.)
• Write a short brief of the notification service(NS) information(price, usage, frequent etc.)
• Fork repository, install reqs, setup env
• Write tests of the NS code, please stick TDD
• Implement the code
• Open PR, please bump the version in setup.py

You can reach me out in any step.
