CNV-51521 | Fix Incomplete transfer of change blocks leads to data corruption

Issue: When user has a large disk with over 2000 changed blocks the
QueryChangedDiskAreas returns only first 2000 changed blocks. The disk
is not getting all the changes form the VMware Change Block Tracking and
this can cause disk corruption.

Fix: Query the changed areas by every 2000 block chunks, combine the chunks
together and request the next QueryChangedDiskAreas to start from the
end of the last block. Once the QueryChangedDiskAreas will return less
than 2000 blocks we know that it was the last chunk and can continue
with the disk import.
