[Kafka Connect] Add options to change log levels

[yeikel]

Issue submitter TODO list

• [X] I've searched for an already existing issues here
• [X] I'm running a supported version of the application which is listed here and the feature is not present there

Is your proposal related to a problem?

Yes, it is often necessary to change the log levels of Kafka connect at runtime during development and debugging. Currently, I need to multi task between the UI and the Kafka Connect REST API as this feature is not exposed in the UI

Describe the feature you're interested in

The goal of this feature request is to expose UI elements to access the different endpoints that the API exposes that can be used to adjust the log levels. Example features include :

1. Check log levels
2. Get the log level for a specific logger and/or connector
3. Change the log level for a specific logger and/or connector

Describe alternatives you've considered

Currently, the only option I have is to interact directly with the Kafka Connect API
