Describe the issue you're reporting

Consider this PR #43584, where we enrich CloudTrail logs with new attributes. Once of the conversations on the PR was on the naming of the attributes - #43584 (comment)

The proposal here is to move CloudTrail logs' userIdentity bound attributes (see official documentation for existing attributes ¹), which are not mapped through Semantic Conventions (e.g: userIdentity.userName as user.name) under aws.user_identity. And this is to preserve a hint of the origin of the mentioned log attributes.
