APPC - OAM ConcurrentModificationException

APPC - OAM ConcurrentModificationException

Fixes:

- In the AsyncTaskHelper, the cancel future augmentation in the
scheduleBaseRunnable(...) removed itself from the myFutureSet while
it was iterating over the entries. This caused the
ConcurrentModificationException

- The Timeout operation in the ConfigurationHelper was not converting
the units to millisecond.

- The Timeout in the BaseProcessor. preProcess(...) was NOT using the
request-timeout value supplied in the request.

- When a timeout occurred in the BaseProcessor. preProcess(...) method,
the OAM state was not being switched to ERROR state
