ErroredReplicationTask is a special kind of NoopReplicationTask in that it
is not actionable, and wraps an error that might have occurred during Task
instantiation time. This is used to protect "future" events that we know
nothing about from breaking the system by throwing IllegalStateExceptions.

Whether or not the user intends to do something with these tasks and act
upon the exceptions is left to the user to determine how they can best use them.
