Make Redis persistence settings configurable
As part of https://gitlab.com/gitlab-com/infrastructure/issues/2448 I should configure a Redis server to be volatile and not write a single piece of data to the disk.
Alas, according to the code this isn't currently supported in Omnibus.
Is this something we'd like to look into? If yes, what kind of timeline can I expect?
As always, poke me if you need any help!
