A short question. I saw a few projects are using the name 'ca_file' [1] as config option, while others are using 'cafile' [2]. I wonder what is the flavorite name convention?

I asked this question because Kolla developer suggested Zun to rename from 'ca_file' to 'cafile' to avoid the confusion [3]. I want to confirm if this is a good idea from Keystone's perspective. Thanks.

Best regards,
