Simpilifer/Complexifier changes for Broadcast OTA update
Fix tests broken by events timezone changes
Make eventSimplifier nullable in ContentModelSimplifier, simplifying simplifier test.
Default percentage failure for controller job
Refactor of Events code following code review
 - Split of EventsUtility
 - Split out of BtDataTransformer from S3BtEventsDataFetcher
 - Logic for fetching an S3 file moved into helper class
 - refactor of packages on BT events:
    - model renamed to feedModel
    - new model package created for actual model
 - removal of unused *Configuration classes
Second refactoring stage of Events code
 - FieldMapper split - topic resolving function now in separate class
 - much of location resolution moved up to common EventDataHandler class
 - there is now an ignore list for team names and locations, for test data and the like that
shouldn't be ingested.
 - when mapping doesn't contain appropriate value for location, the ingester throws, failing the job
Fix up code after rebase
Merge branch 'events-refactor' into stage
