Improving the Grok circular reference check to prevent stack overflow (#1079)
This change refactors the circular reference check in the Grok processor class
to use a formal depth-first traversal. It also includes a logic update to
prevent a stack overflow in one scenario and a check for malformed patterns.
This bugfix addresses CVE-2021-22144.
