On previous versions of the OneView client, the polling of changes
on OneView was done until a certain amount of tries then stopped
even for tasks that are ongoing. This patch changes that behavior
to keep checking tasks until completion and use the
max_polling_attempts parameter only for exceptional cases such as
request errors/timeouts.
