✨ [RUM-3902] Add privacy control for action names

[cy-moi]

Motivation

To be consistent with session Replay and ease the customer configuration, we could use the same privacy options as Replay. To avoid breaking changes, we need to add an extra init option that indicates the action names should take into account the defaultPrivacyLevel and the HTML overrides.

Desired behavior

When the user opt-in for enablePrivacyForActionName, we mask action names when no action name attributes given and no html override.

When the user does not opt-in for this feature, we mask action names when html override is set.

Changes

Add an opt-in field enablePrivacyForActionName: boolean in configuration. Once enablePrivacyForActionName: true, the action name computation would behave (taking into account of all privacy configs) as follow:

Header	Header
allow	The action names are collected
mask	The action names are not collected
mask-user-input	The action names are collected since we don’t rely on the user input value to compute the action name
hidden	The actions are not collected

This also works for html override data-dd-privacy accordingly.

Testing

• Local
• Staging
• Unit
• End to end
