Automatically remove potential PII from report data

[maxmilton]

Sometimes report data contains text that could be potentially be seen as personally identifiable information (PII). A typical example is system paths in URLs e.g.,:

/home/username/Downloads

... where "username" could be PII. It would be nice if we can create an incoming data filter that replaces PII. It should run on all incoming data. This should probably be configurable per-project. For example, the above could be:

/home/[Redacted]/Downloads

Or some other placeholder; REDACTED, [REDACTED], <REDACTED>, __REDACTED__, etc.
