`enable_syslog=false` does nothing.

I turned off logging via syslog, but it still logs via it

https://developer.hashicorp.com/consul/docs/agent/config/config-files#enable_syslog

It is not clear how to reconfigure logging via files.

config file

```
$ cat /etc/consul.d/consul.hcl
# https://developer.hashicorp.com/consul/docs/agent#configuring-consul-agents
datacenter = "dc1"

data_dir = "/opt/consul/data"
server = true # Agent mode
bootstrap_expect = SERVER_COUNT # Ignored in client mode
retry_join = ["RETRY_JOIN"] # The default value comes from `aws/variables.tf` file

# DNS
domain = "prd.plntr.ca"
# recursors = [ "8.8.8.8" ]
client_addr = "0.0.0.0"

# addresses = { }
bind_addr = "0.0.0.0"
advertise_addr = "IP_ADDRESS"

acl {
enabled = false
default_policy = "allow"
down_policy = "extend-cache"
}

# Logging

enable_debug = true
log_level = "trace"
enable_syslog = false
log_rotate_max_files = 30
log_rotate_duration = "24h"

ui_config {

Start with the `/etc/consul.d/consul.hcl` configuration and the `/etc/systemd/system/consul.service` entry point, then reproduce the behavior using `consul agent -config-dir="/etc/consul.d"`. Compare the documented `enable_syslog` setting with the agent's logging behavior; done means disabling it either stops syslog output or produces clear documentation of the required configuration.
