Find the {@link OnNextFailureStrategy} to apply to the calling operator (which could be a local
error mode defined in the {@link Context}) and apply it.

@param error The error.
@param context The most significant {@link Context} in which to look for an {@link OnNextFailureStrategy}.
@param subscriptionForCancel The {@link Subscription} that should be cancelled if the
strategy is terminal. Null to ignore (for poll, use {@link #onNextPollError(Object, Throwable, Context)}
rather than passing null).
@param <T> The type of the value causing the error.
@return a {@link Throwable} to propagate through onError if the strategy is
terminal and cancelled the subscription, null if not.
Find the { @link OnNextFailureStrategy } to apply to the calling operator ( which could be a local error mode defined in the { @link Context } ) and apply it .
