Allow masking PII

[bcaudan]

Currently PII can be sent with some of the collected data:

• url
• error message / stack
• user action name

Add a way to mask them for both logs and rum SDK.

Just wanted to add a thumbs up, currently the lack of this feature is blocking us from using rum 😞

You now have access to the beforeSend scrubbing API starting with v2.1.0 of the Browser SDK. See how to use it in the documentation but if you really can't wait, here's an example:

window.DD_RUM &&
    window.DD_RUM.init({
        ...,
        beforeSend: (event) => {
            // remove email from view url
            event.view.url = event.view.url.replace(/email=[^&]*/, "email=REDACTED")
        },
        ...
    });

Thank you for your patience and let us know what you think about it :)
