Set max req count before applying rate limit

[DrizzlyOwl]

• Exposes a variable that can be adjusted to raise or lower the threshold of incoming requests before a WAF rate limit is applied.
• The container app module sets the time range to 1 minute, so with this default value there must be at least 300reqs/min before a rate limit is applied.
• This mirrors the same default as is set in the container app module
• This will likely be raised in Production when we have real-world traffic consuming the API.
