Organization audit logs should show users being added to default groups when first invited to a site

Problem Definition

Users invited for the first time to a cloud site and granted access to any number of products (and thus placed in those product's default group(s)) will not have a log specifically showing that the user was added to those product's default group(s).

Suggested Solution

When a user is invited to a cloud site and granted access to any number of products, log that the user was added to those default groups.

Why this is important

Allows admins to quickly confirm how, when and why a user was added to a default group.

Workaround

There is no workaround at the moment.

Generally, the "user was invited to your site/product" organization audit log message implies that the user was added to the default groups of that product.
