Prevent Pode from writing verbose messages to the system/journal logs

[Clifra-Jones]

Describe the Feature

Pode writes a lot of verbose messages to the system logs. This makes it hard to trouble shoot if there is a problem, especially if Pode is started as a SystemD service. The majority of what is written there looks like development related information, not operational data.

Can we add a parameter to minimize the output written to the system and journal logs?

OK, I have found the answer to this and it had nothing to do with Pode or Pode.Web.

This is normal operation for powershell on Linux. This becomes expecially evident with the large use of script blocks that Pode and Pode.Web use.
This output doesn't go to standard out or any other output stream it writes directly to the system log.
If you are running powrshell as a service (unit file) it writes directly to the journal.

You can stop this very verbose logging using the following method.

Edit or create the file 'powershell.config.json' in the $PSHome directory.
For most Linux distributions this will be in /opt/microsoft/powershell/7

Add the following json to this file.

{
  "ModuleLogging": {
    "EnableModuleLogging": false
  },
  "ScriptBlockLogging": {
    "EnableScriptBlockInvocationLogging": false,
    "EnableScriptBlockLogging": false
  },
  "LogLevel": "error"
}

What this does:

1. Turns off module loggin for all module.
2. Disables Script Block Logging and Script Block Invocation Logging

This now stops all the nonsense from being logged to the systemd journal and the system log.
