New replace_values Remap function

[binarylogic]

Blocked in #5785. Like #5377, but for values instead of keys. Please see #5377 (comment), since this should be an event-level function:

Example

Given this event:

{
	"payment": {
		"number": "4485216652919430"
	}
}

And this Remap expression:

redact_values(redactor = "full", patterns = ['credit_card'])

(see the redact function)

The following event would be produced:

{
	"payment": {
		"number": "****"
	}
}

Requirements

• The arguments should match the redact function.

Closing since this is supported by VRL iteration now.
