Description of problem:
The Values of spec.memory.guest in the VirtualMachineClusterInstancetype we deploy are not consistent with the names of the resources series.

example:
u1.large memory = 8Gi
m1.large memory = 16Gi
cx1.large memory =4Gi

Version-Release number of selected component (if applicable):
CNV 4.14.0

How reproducible:
100%

Actual results:
All the VirtualMachineClusterInstancetype with the "large" suffix have different values in spec.memory.guest

Expected results:
All of the series should have the same values in the memory when using the same "suffix" resource
