netapp image cache cleaning start thresholds does not work

[Yukihiro KAWADA]

netapp image cache cleaning start thresholds does not work.

Image cache cleaning start thresholds can set
self.configuration.thres_avl_size_perc_start.
This default value is 20(%).
But this value is not used at all.

avl_percent = int((total_avl / total_size) * 100)
Because this avl_percent is always zero.
And cleaning process will start every time without
waiting for the remaining 20% capacity.

Correct code is:
avl_percent = int((float(total_avl) / total_size) * 100) # Y.Kawada
