Ability to restrict Team Calendar events and event types from specific users/groups

Problem Definition

Currently, all events on a Team Calendar can be viewed by all users of the calendar. It is not currently possible to restrict an event or event types to/from specific users, the way that Confluence pages can be restricted

Suggested Solution

Provide ability to restrict events and event types to or from users and/or groups

Why this is important

Better ease of use and matches what we are already doing for the rest of Confluence
