Make access_log for main configurable

[hafe]

Is your feature request related to a problem? Please describe.
Currently it is not possible to globally configure log forward of access logs in a simple way. Logging high volume access logs to stdout means that they get forwarded to the log stack in Kubernetes. This can be problematic depending on the stack.

Describe the solution you'd like
Add a directive to the global Config map where the main access_log directive can be overridden

Describe alternatives you've considered
An alternative solution is to use a custom main template which is far from simple.

Hi @hafe ,

We had a chance to discuss this issue and I want to add some context.

The future state is to integrate with OpenTelemetry and streaming logs using it. We are planning on it but we do not have a timeline for this work.

Until we get to a more robust solution we are happy to accept your contribution with some conditions:

1 - We need a flag to enable the access log
2 - The default access log is always off
3 - We must block any configuration that allows logging to files

Please let us know what you think about it?

[hafe]

Let's see:

1. already exist
2. is the inverse of today's default, I don't understand?
3. I can see if I can add some validation to not allow file

[danielnginx]

Apologies, I should mention that I was looking in the PR.

Keep the flag as it is AccessLogOff.

Allow the access_log configuration but preventing logging to files.

[hafe]

Check latest version, only allows syslog
