Adds a concept to show that Azure Service Bus Legacy and the old RabbitMQ transports are removed, and a check so that if the transport is removed and doesn't have an auto-upgrade path, it can't be installed/upgraded.
A lot of the pre-install and pre-upgrade checks were scattered and duplicated all over. This centralizes all those checks.
However, this PR does not do a similar dedupe process on the PowerShell cmdlets.
