Adds sampling on authorizationMetrics logs

[danzanzini]

What is the purpose of this pull request?

This PR adds sampling to the authorizationMetrics directive logs.

What problem is this solving?

We found that logs with the message Private route being accessed by unauthorized user are responsible for sending 3GB of data to Splunk by hour.

So, this PR adds a random function to reduce the amount 100x, decreasing the amount logged to 30MB per hour.

How should this be manually tested?

Nothing should have changed, and the amount logged should decrease
