NIFI-4151: Updated UpdateAttribute to only create JAXB Context once; …
…Minor performance tweaks to standard validators and
StatusMerge.prettyPrint; updated AbstractConfiguredComponent to not create a
new ValidationContext each time that validate is called but only when needed;
updated FlowController, StandardControllerServiceProvider, and
StandardProcessGroup so that component lookups can be performed using a
ConcurrentMap at FlowController level instead of having to perform a
depth-first search through all ProcessGroups when calling findProcessor(),
findProcessGroup(), findXYZ()
