Enhance method manageDatabase.getClusters to take enum KafkaClustersType instead of string

[muralibasani]

What is currently missing?

manageDatabase.getClusters and other methods where kafka clusters type enum can be passed as an argument instead of string, for better visibility and quality

How could this be improved?

Pass enum instead of string

Is this a feature you would work on yourself?
