ApplicationAttemptId of the application to which the
Container was assigned.
Note: If containers are kept alive across application attempts via
ApplicationSubmissionContext.setKeepContainersAcrossApplicationAttempts(boolean)
the ContainerId does not necessarily contain the current
running application attempt's ApplicationAttemptId This
container can be allocated by previously exited application attempt and
managed by the current running attempt thus have the previous application
attempt's ApplicationAttemptId.
