I think if reload is true, we shouldn't even write out the parameters to the flow definition

I think if reload is true, we shouldn't even write out the parameters to the flow definition

I'm not sure it's a good idea, we should be able to see the parameters in the flow definition. It's useful for the user to see what parameters are used in the flow configuration in runtime and can be useful for debugging purposes as well.

This value would more realistically be property_encryption::encrypt("old_secret_minifi_data_value", encryption_provider), right? I think we could do that with a fmt::format().

If you want to leave it as it is for simplicity, that's fine, too, but then maybe change it to something like "old_secret_minifi_data_value_encrypted".

parameter_context_names is unused, could be removed (in the YAML version, too)
