Why is this one not configurable? Comparing to PARAM_BREAK_AFTER?

It's also necessary to update setup:config:set with new params (in \Magento\Setup\Model\ConfigOptionsList\Session).

Could you please also update http://devdocs.magento.com/guides/v2.2/config-guide/redis/redis-session.html ?

I copied DEFAULT_FAIL_AFTER from 2.2-develop https://github.com/magento/magento2/blob/0839bd421bd5812e9aa7c943b89ecae9d5008832/lib/internal/Magento/Framework/Session/SaveHandler/Redis/Config.php#L121 Should I change it to be configurable here?

Thanks for pointing out the changes required to setup:config:set. I'll get that taken care of.

Got it... ok, let's leave it as is.
