Redis Better print information with info

Basic redis-server infomation

redis_version:7.0.7

redis_build_id:2260280010e18db8

When I use info to show maxmemory policy I got below

maxmemory_human:16.00G
maxmemory_policy:volatile-lru

so I try to set the maxmemory_policy config in command with config set maxmemory_policy volatile-lru but it failed. because the proper command should be config set maxmemory-policy volatile-lru. so could we print the maxmemory-policy instead of maxmemory_policy when we type info?

127.0.0.1:9195> config set maxmemory_policy volatile-lru
(error) ERR Unknown option or number of arguments for CONFIG SET - 'maxmemory_policy'

Unfortunately it would be a breaking change. It would break scripts that parse these info fields.

Another possibilty is to make config set more tolerant and make it accept maxmemory_policy an alias for maxmemory-policy and similar for other config options. I don't know if it would be acceptable.

right, we can't change these now.
