Allow for logfile naming like in Nomad #15709
Description
Feature Description
Currently consul logs files like this consul-{timestamp}.log
This is a pain to figure out the most recent log file. Sure we collect files and ship them out but sometimes it's useful to look inside /var/log
Nomad Example
ls -alh /var/log/nomad/
-rw-r-----. 1 root root 51K Dec 6 01:50 nomad-1670313323123267918.log
-rw-r-----. 1 root root 12K Dec 7 01:50 nomad-1670399732186160816.log
-rw-r-----. 1 root root 16K Dec 7 09:55 nomad.log
But consul looks like this
ls -alh /var/log/consul/
drwxr-xr-x. 2 consul consul 4.0K Dec 7 08:34 .
drwxr-xr-x. 24 root root 8.0K Dec 7 08:34 ..
-rw-r-----. 1 consul consul 39K Dec 1 11:35 consul-1669914326514455232.log
-rw-r-----. 1 consul consul 230K Dec 2 11:35 consul-1669916117380991503.log
