The problem/use-case that the feature addresses
Running Redis 7.0.9 in a container. The novel logging format Redis currently employs presents friction to slurping its log output into monitoring.

Description of the feature
A configuration option that allows us to configure Redis to output its logs in at least one of JSON and logfmt.
Either of these formats are eminently grokkable by telemetry collection systems like fluentd, telegraf, promtail.
Having this option would make Redis more fluidly friendly with our systems, and allow us to more easily and reliably alert on errors and warnings.

Thanks!
