refactor: modify cf observability config to decrease logs generated

[matthewvolk]

What/Why?

Recent load testing generated over 6 million logs on a single Catalyst deployment; this is quite a large number considering that the base paid plan only gets 20M logs for free, then requires that you pay for each million logs after that. In this PR we are primarily disabling invocation logs and lowering the sampling rate from the default (1) to 0.05 to decrease the number of logs emitted by a Catalyst deployment.

Testing

Will be tested during the next load test
