Bug 1758565

Description of problem:

From the Engine Web GUI filtering function in:
Compute --> Virtual Machines --> Vms: compatibility_level 
return the "vms.cluster_compatibility_version" instead of "vms.custom_compatibility_version"

Query performed on the database is:

~~~
:
...method: getAllUsingQuery, params: [SELECT * FROM ((SELECT  vms.* FROM  vms   WHERE  vms.cluster_compatibility_version ILIKE '4.1' )  ORDER BY vm_name ASC ) as T1 OFFSET (1 -1) LIMIT 100]...
:
~~~

It should be:

~~~
SELECT * FROM ((SELECT  vms.* FROM  vms   WHERE  vms.custom_compatibility_version ILIKE '4.1' 
~~~

Version-Release number of selected component (if applicable):

RHV 4.2 (4.2.7.4)

How reproducible:

Try to apply a filter on "Compute --> Virtual Machines --> Vms: compatibility_level = "<custom_compatibility_version>". where VMs have minor compatibility version compared to the cluster compatibility version.


Steps to Reproduce:
1.Login to RHV
2.Select 'Compute' --> 'Virtual Machines'
3.Type in filter textbox -- >compatibility_level = "<custom_compatibility_version>"

Actual results:

Currently even if there are VMs with a custom_compatibility_version these are not returned when filter is applied  

Expected results:

When a filter on a given custom_compatibility_version is applied the search should return the VMs with that custom_compatibility_version
