Block volume shrink on Xen

[JoaoJandre]

Description

On version 4.16.1.0 PR #5829 blocked volume shrinking via UI when using XenServer. However, this change was not sufficient, as the user may still use the APIs directly to try to shrink their volume. Furthermore, via UI, it is still possible to inform the shrink option when changing disk offerings. This PR removes that option from the UI; also, the resizeVolume and changeOfferingForVolume APIs were changed to block this type of operation when using XenServer, similar to what is done when using QCOW2.

Test Description

Via UI, I validated that the shrink option no longer appears for XenServer volumes:

• Before:
  

• After:
  

Via CMK, I validated that both APIs block the use of the parameter for XenServer:

I also verified that the APIs still work correctly without using shrink:

looks good, not sure if it needs further testing. let’s run tests again to satisfy my insanity:
