Remove trace lines about NO_COLOR.

[qbit]

Currently there is a warning for every command run when NO_COLOR is set. For example:

$ headscale nodes 
{"level":"trace","time":"2021-09-12T07:31:48-06:00","message":"NO_COLOR is set, disabling colors"}
Manage the nodes of Headscale

Usage:
  headscale nodes [command]

Available Commands:
  delete      Delete a node
  list        List the nodes in a given namespace
  register    Registers a machine to your network
  share       Shares a node from the current namespace to the specified one

Flags:
  -h, --help               help for nodes
  -n, --namespace string   Namespace

Global Flags:
  -o, --output string   Output format. Empty for human-readable, 'json' or 'json-line'

Use "headscale nodes [command] --help" for more information about a command.
$

This disables that.

I don't have strong opinions of this, iirc this might be set up before the log level?

If it can disabled by setting lower than tracing, I would suggest that rather than removing.

I am using the default log level - and the output happens on the command line.

Personally - I think it's annoying. I know I have color disabled, I set NO_COLOR explicitly and any thing that is informing me of that is just adding noise.

[qbit]

by "default log level" I mean I have nothing explicitly set in my config.json that increases or decreases the logging.

Your right, the lines are printed before we set the log level, let's just remove them
