[shyam0904a]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Currently checks are made to check if waf fail open is configured but there are cases where waf fail open is set to true but does not have a waf web acl associated with it.

Describe alternatives you've considered
A new control that can check for elb/elbv2 for its association with wafv2
