[FR] Support path in Additional Ignored Sources in CSP setting

[olksdr]

Currently we support filtering sources based on schema, domain and port but not on the file path.

We should look into supporting the file path, as in some cases customers want to filter those coming in from different domains.

Right now if the file path in provided , e.g. */example.js the Relay will interpret it like a only * (catch all) and will ignore all the incoming events.

The part of this issue is to update/improve the documentation.
