* PMM-11387 Fixed resource types from DecimalSI to BinarySI

DecimalSI calculation does not work for PXC clusters with fraction
values. PXC gives the calculated "2.4G" is not valid and if I manually override that
to 3G it is working fine.

* Revert "PMM-11387 Fixed resource types from DecimalSI to BinarySI"

This reverts commit 4a36502.
