Optimize getEvent methods to decrease query time

[jallentxbiomed]

• getAllPackageCategories will return a cached map of packageCategories to refrain from retrieving them for each package
• New method override for addExtraFieldsToPackage to getextraFields for packages before any other operation to save from retrieving it every time
• getFullPackages and getFullPackage get the package info from cached superPackages instead of database
• New getEvent override method that uses the more optimized narrativeCache methods to get event info

• getAllFullSuperPkgs now accounts for either full database if eventId is null or select superPkgs for an eventId
• getAllEventData now receives a cached map of eventData objects instead of recursively retrieving eventData from database every time
• getChildEventData receives cached map instead of querying database
• SNDServiceImpl now calls the new override method for getEvent
