    @serg38 and I found out a way to change this property from UI, inserting the property
in "configuration" table with scope="Cluster", insert sql:
    
    INSERT INTO `cloud`.`configuration` 
    (`category`, `instance`, `component`, `name`, `description`, `default_value`, `updated`,
`scope`, `is_dynamic`) VALUES 
    ('Advanced', 'DEFAULT', ‘CapacityManager', 'cluster.storage.operations.exclude', 'Exclude
cluster from storage operations', 'false', now(), 'Cluster', '1');
    
    This way, all clusters will be inheriting the property in its default value, which is
false. So if you want to set it true, you can do it from UI, and will be inserted in "cluster_details"
table with value = true.

> h1. Introduction
> In some environments there is a need to exclude certain VMware clusters from performing
OVF operations. This operations are part of: 
> * create template
> * create volume snaphsot
> * copy template, volume, images from primary storage to secondary storage
> * migrate volume 
> * participate when a template gets cached over to primary storage.
> In ESX/ESXi, OVF operations are low priority and bound to a single CPU and most likely
get throttled to certain IOPS and network limits. 
> If the hypervisor chosen for OVF operations is weak or overloaded this results in significantly
longer execution of such OVF command and therefore degraded performance of underlying CloudStack
API call.
> h2. Proposed solution
> It is proposed to add a way to exclude hosts from selected clusters for OVF operations.
> To exclude a cluster, would be necessary to insert a record in {{cluster_details}} specifying
property *{{'vmware.exclude_from_ovf'}}* in this way: (supposing we want to exclude cluster
X)
> ||cluster_id||||name||value||
> |X|vmware.exclude_from_ovf|true|
