Change kubevirt behaviour for target Pod: add 60Mi more memory to the target Pod resource requirements depending on coreFraction value: - Increase requests and limits if cpu cores are guaranteed (coreFraction = 100%) - Increase limits only if cpu cores are not guaranteed (coreFraction < 100%).

Description
Change kubevirt behaviour for target Pod: add 60Mi more memory to the target Pod resource requirements depending on coreFraction value:
See deckhouse/3p-kubevirt#66
Why do we need it, and what problem does it solve?
This additional memory should prevent OOMKills for the target Pod during VM migration with hotplugged disks.
What is the expected result?
VM with 16 hotplugged disks migrates with no OOMKills.
