- Remove isPathologicalRegex function and replace with MatchTimeout
- Simplify parseFilter by relying on runtime timeout protection
- Add comprehensive timeout test for pathological regex patterns
- Set 5-second timeout for all compiled regex operations
In this PR I removed the regex pattern length restriction because from
multi value variables this length can be easly reached, also if the
regex is going to be too long it will be caught in the timeout.
Fixes#2086
