Missing wrapper for 'config'

[dzvancuks]

Missing config_set and config_get. This is needed in case I need to set pub-sub channel notifications, see https://redis.io/docs/latest/develop/use/keyspace-notifications/

config set notify-keyspace-events KEA

This could also be possible to do if library would have an ability to execute Redis commands directly. Something like

| ${command_result} | Execute | ${redis_conn} | Some Redis command

${command_result}    Execute    ${redis_conn}    CONFIG SET notify-keyspace-events KEA

Perhaps I'm missing it. Is there anything similar already in this library?
