* Expose resource_reaches_status' retry options
resource_reaches_status is used in many places to monitor many
different kinds of OpenStack resource. It is reasonable to expect a
flavor to be created in a few seconds where as an image based instance
may take minutes to become active. With that in mind this change
exposes the retry options used by tenacity allowing the caller to
set reasonable expectations for the resource state change.
In addition the image based instance creation call is updated
to retry for longer as this has been timing out.
