[redhat-lspp] CUPS configuration: Get-Notifications

Something that occurred to me today is that for LSPP, CUPS should be
configured to restrict the IPP notification operations:

Create-Subscription
Renew-Subscription
Get-Notifications

Otherwise, information about jobs and printers can be discovered.  The
way subscriptions work is that I make an IPP connection to the local
CUPS server is made, and a 'Create-Subscription' operation sets up the
list of events to notify me of.  Then, later, a 'Get-Notifications'
operation retrieves a list of events such as job-created, printer-added.
These events carry information such as job IDs, job names etc.
