Simplify enabling Sentry logging

[Litarnus]

Problem Statement

To enable logs it's currently necessary to define the service and monolog handler before setting enable_logs to true, otherwise the option will not work properly.

Solution Brainstorm

Investigate if adding a default service and handler makes sense so that enable_logs itself is sufficient to see logs in Sentry
