Describe the bug
There are two similar parameters: brokerDeleteInactiveTopicsFrequencySeconds and brokerServicePurgeInactiveFrequencyInSeconds.
In documentation, brokerDeleteInactiveTopicsFrequencySeconds is recommended. However, brokerServicePurgeInactiveFrequencyInSeconds is implemented in code.

Additional context
We need deprecate one of them, make it consistent in code and documentation.
