For epic #26845 Investigate which attributes can be updated after checkpoint and before restore.

Currently the following attributes under Performance in HttpSession cannot be updated between checkpoint/restore.

appInCacheName
cacheSeparator
scheduleInvalidationFirstHour
scheduleInvalidationSecondHour
writeContents
writeFrequency
writeInterval

After discussion with @zhang-ca and @tjwatson, decided to log a warning message when these are attributes are modified at restore. Since there is a very little probability of user updating these config properties at deployment time in a container environment.
