Sensitive keys denylist

[priettt]

Goal

If a sensitive_keys_denylist is provided in embrace-config.json, the following components will be scanned:

• Moments (if not removed by time we implement this)
• Session properties
• Log attrs + log event attributes
• Span attrs + span event attributes
• Event attributes

If the key in any of those properties is present in the denylist, the value will be changed to .
