Enabling CDC messes up mgmt-api configuration

[burmanm]

What happened?
management-api uses properties to handle how the JVM_OPTS is modified. Enabling CDC messes up this behavior and causes things that are not supposed to be there to re-appear or go missing. For example, MGMT_API_DISABLE_MCAC should not cause MCAC to appear.

The entire generate_config.go should probably be history at some point and the configuration of the startup properties should happen in the mgmt-api repository.

Did you expect to see something different?
