update ui to help prevent admin users from deleting customer connections

[jonstout]

As an admin workgroup member, users have the ability to enter into any other workgroup's context. When making changes within these contexts, it's important that users understand they're making network changes oh behalf of other users outside their normally used network domain. This would be used primarily to prevent admin users from accidentally deleting customer connections.

The first step would be to tag all workgroups that a user is not explicitly added to as auto-generated. The second step is to decide what/wow we indicate this to users.

Updated the confirm dialogs in #1124 to provide users an additional chance to ensure the expected connection is being modified.

An additional indicator may be provided by placing a header on all pages whenever a workgroup is selected which the user hasn't been explicitly added to. Not sure if the benefits will outweigh the dev costs. @ajragusa thoughts?
