> ManagedState: Add a disable purging option

> Have an option that can disable purging of data.
> Currently the TimeBucketAssigner moves time boundary periodically based on
> system time as well as based on event time. This is error prone and moving
> time boundary periodically implies that data will always be purged.
> The change that needs to be made to TimeBucketAssigner is to just move time
> boundary when there are future events that don't fall in that boundary. This
> will imply that if there are no events outside the current boundary then data
> will not be purged.
> ManagedStateImpl uses processing time for an event, so moving boundaries
> based on system time is going to happen there nevertheless.
