Bug fixes

• Fixed control and query name by renaming elb_application_lb_drop_http_headers to elb_application_lb_http_drop_invalid_header_enabled to correctly indicate that it checks whether Application Load Balancers are configured to drop invalid HTTP headers (not all headers). (#936)
• Fixed the iam_policy_no_full_access_to_kms control to correctly reference iam_policy_no_full_access_to_kms query instead of iam_policy_no_full_access_to_cloudtrail. (#938)
