Regex Filter

[XAMPPRocky]

Pretty straightforward addition. A filter that uses regex::bytes::Regex to filter or capture bytes.

Config Options

• regex: The actual regular expression.
• capture_key: The key to store any capture groups that matched to in metadata.
• on_success: What happens when the regular expression succeeds. My current thinking is this would accept pass and capture, pass where the filter continues on, and capture where it additionally places any capture groups in capture_key.
• on_error: Right now I think this would have a single value drop where the packet is dropped, but in the future this could have values like ban or event when we have Rules and Actions based on Filter events #63.
