Avoid setting a default for bandwidthPerMigration and dropping it if == 64Mi #1567

In the past we were setting a default of 64Mi for
spec.livemigrationconfig.bandwidthpermigration but
the value was simply ignored by kubevirt due to
an ancient bug.
Now the bug on kubevirt/kubevirt got fixed and
unfortunately we discover that the default that
kubevirt and then HCO set in the past doesn't
fit production use cases.

Let's avoid setting a default for
spec.livemigrationconfig.bandwidthpermigration
and let's explicitly delete it on upgrades
if set to "64Mi" which is not acceptable.
