Introduce virtualMachineOptions to hco cr (#2356)

VirtualMachineOptions holds the cluster level information regarding the virtual machine.
This defines the default behavior of some features related to the virtual machines.
- `DisableFreePageReporting`
  With freePageReporting the guest OS informs the hypervisor about pages which are not
in use by the guest anymore. The hypervisor can use this information for freeing these pages.

  freePageReporting is an attribute that can be defined at [Memory balloon device](https://libvirt.org/formatdomain.html#memory-balloon-device)
in libvirt. freePageReporting will NOT be enabled for the vmis which does not have the Memballoon driver,
OR which are requesting any high performance components. A vmi is considered as high performance if one of the following is true:
  - the vmi requests a dedicated cpu.
  - the realtime flag is enabled.
  - the vmi requests hugepages.

  With `DisableFreePageReporting` freePageReporting will never be enabled in any vmi.
`DisableFreePageReporting` is an empty struct and freePageReporting is disabled by default.
