Migeng 327 avoid crashes based on issues use cases

[jonathanvila]

There are 3 issues covered inside :

• VM without HOST
• HOST without CLUSTER
• HOST or VM without Total CPUs

These issues can happen because the attribute doesnt exist , or because it has the wrong value type.
Also this PR includes a Handler used to log the details of those Exceptions , but can be extended to persite the info in DB, etc.
Every use case has a json file in resources folder and EndToEnd test uses them to execute the analysis and then asses the values received.

This PR is blocked by https://issues.redhat.com/browse/MIGENG-328 , as there are some changes to do in xavier-analytics to relax the filtering out of vms if certain fields are null
