Allow for per-day log names for inbuild log rotation.

Preferably with inbuilt gzipping of the previous day's log and an option to remove logs past a certain date, but appreciate these two requests are optional and can be solved easily by the use of other plugins.

For reference I am using the Server set of placeholders and the following configuration:
DiscordConsoleChannelUsageLog: "logs/discord-commands-%server_time_yyyy-MM-dd%.log"
