Decorate harvest requests with ht (hasTrace) param
Decorate with ht (hasTrace) query param for all harvest requests except for blobs and logs endpoints. This helps support searching for browser data with associated tracing data.

v1.281.0
Features
Capture Nearest UserAction Fields
The UserAction feature has been extended to capture "nearest" field values when the UserAction target does not include the desired fields. To facilitate this, a configuration was added allowing the user to control what fields are collected, specified as init.user_actions.elementAttributes: []. When empty, no extra fields will be collected. When supplied, the target will be checked for each property. This configuration defaults to ['id', 'className', 'tagName', 'type'], which matches the fields captured before this change.
For each elementAttribute defined, if the property is not found, the agent will search up the parent tree of the target element, until the property is found. If found up the parent tree, a property called "nearest" + fieldName will be added to the event.
