Cherry-pick #18389 to 7.x: Remove unused flag in Checkpoint module configuration

[adriansr]

Cherry-pick of PR #18389 to 7.x branch. Original message:

What does this PR do?

This removes references to var.log_level in checkpoint module's configuration. This variable is not used, just a left-over from using the cisco module as a base.

Why is it important?

Avoid confusing users with a configuration option that does nothing and references docs from a different vendor.
