Increase interval for periodic full checkpoints from every 12 minutes
to every 15 minutes. This change saves CPU cycles. Once the full
checkpoint is sent any changes are handled via micro-checkpoints.

CSCug23975 - VoLTE: Prioritized handling of VoLTE/Emergency calls
Applicable Products: LTE
Feature Changes
Prioritized Handling of for VoLTE/Emergency Calls
If prioritized APN/ARP handling is enabled and if the APN/ARP received in CSReq matches any of the configured
prioritized APN/ARP values, any valid CSReq will not be rejected because of congestion control.
prioritized APN/ARP values, any valid CSReq will not be rejected because of congestion control.
In summary, prioritized calls will not be rejected due to congestion.
