### problem
When a migration is initiated from Cloudstack and for some reason the target
host does not have the config.product property, an NPE is thrown in the logs
failing the migration. Unfortunately we do not know the exact steps to get into
such state, but surely we can address the NPE with some defensive coding

### versions
VMware 8.0
ACS 4.18.2.3
### The steps to reproduce the bug
NA
### What to do about it?
This problem could be mitigated by:
1. restarting
/etc/init.d/hostd restart
/etc/init.d/vpxa restart
2. Out of bound migration directly in vCenter, while cloudstack would sync
up a bit later.
